force of 5000N is acting on a body of mass 50kg if force of friction on the body is 100N. Calculate how long it takes for the body to gain the velocity of 50m/s from rest
Answer:
.5102 s
Explanation:
Net force acting to accelerate the body is 5000- 100 = 4900 N
F = ma
4900 N = 50 kg * a then a = 98 m/s^2
v= at
50 m/s = 98 m/s^2 t then t = 50/98 =.5102 s
what is the difference between an sa and an sb galaxy? (select all that apply.)
The difference between an sa and sb galaxy is Sa has a larger nucleus and more tightly wound arms than an Sb.
What is sa Galaxy?Sa galaxies are normal spirals that have narrow, tightly wound arms, which usually are visible because of the presence of interstellar dust and, in many cases, bright stars.
What is sb Galaxy?The arms of sb galaxy are more widely spread than those of the Sa variety and appear less smooth.
Thus, the difference between an sa and sb galaxy is Sa has a larger nucleus and more tightly wound arms than an Sb.

a lunar probe is moving 1670 m/s at a 73.0 angle. it needs to land on the moon 3.71 x 10^8 m away in a 46.0 direction in 8.64 x 10^4 s. what is the magnitude of the acceleration that the engine must produce?
The magnitude of the acceleration that the engine must produce is 0.065 m/s².
What is acceleration?Acceleration is given by the ratio of Resultant or total force acting on any object and the its mass.
It can also be defined as the rate change of velocity with time.
acceleration a = (Δv) / (Δt)
Given is a lunar probe is moving 1670 m/s at a 73° angle. it needs to land on the moon 3.71 x 10⁸ m away in a 46° direction in 8.64 x 10⁴ s.
The initial velocity will be
1670 x cos (73°-46°) = 1487.981 m/s
Using the second equation of motion, we have
s = ut + 1/2 at²
The final velocity will be zero after landing on Moon.
Substituting the values, we have
3.71 x 10⁸= 1487.981 x 8.64 x 10⁴ + 1/2 a ( 8.64 x 10⁴)²
Solving the equation, we get
acceleration, a = 0.065 m/s²
Thus, the magnitude of the acceleration that the engine must produce is 0.065 m/s²

Hi,i need this hurry and correctly please!!!,fake answers i report you.Thanks.
Step-by-step explanation:
Step 1: Formula
10.0 = Meters
800 = Newtons
4.0 = Centre of Gravity
Explanation in words (Short Form)
- We know all the formulas and that we are calculating the least force being applied. We know that balancing the pole at (A) with the weight of the gravity will equal more force at B times 10. So the answer will be 320 N because the B force will equal 3200. If we divide 3200 by 10. The answer will result as 320. So the final answer for this question is 320N
Answer:
Balancing the pole at A with the weight acting at the centre of gravity = 800(4) Force at B multiplied by 10 = 3200 divided by 10 equals 320N
= 320N

A train is traveling west at a velocity of 25 m/s. Another train is traveling east directly toward the west-bound train at a velocity of 15 m/s. The west-bound train blows its whistle with a frequency of 600 Hz when the two trains are 1000 m apart and then blows its whistle again 10 seconds later. For passengers on the east-bound train, how will the perceived frequency of the first whistle compare with the perceived frequency of the second whistle
(a) The frequency observed by the passenger on the east-bound train when they are 1000 m apart is 675.5 Hz.
(b) After 10 seconds, the frequency observed by the passenger on the east-bound train will be greater than the frequency observed when they are 1000 m apart.
Observed frequency
The frequency observed by the passenger on east-bound train is calculated by applying Doppler shift formula.
[tex]f = f_0(\frac{v \pm v_0}{v\pm v_s} )[/tex]
where;
f is observed frequencyf₀ is original frequency or source frequencyv is speed of soundv₀ is speed of observer (positive when moving towards source)vs is source frequency (negative when moving towards observer)when the two trains are 1000 m apart[tex]f = 600(\frac{343 +15}{343-25} )\\\\f = 675.5 \ Hz[/tex]
The frequency observed by the passenger increases with decrease in distance between the two trains.
Thus, after 10 seconds, the frequency observed by the passenger on the east-bound train will be greater than the frequency observed when they are 1000 m apart.

Angular acceleration in the spin cycle of a clothes washer, the drum turns at
635 rev/min. if the lid of the washer is opened, the motor is turned off. if the drum
requires 8.0 s to slow to a stop, what is the angular acceleration of the drum?
The angular acceleration is 531. 98 rad/s
How to calculate angular accelerationUsing the formula:
Angular acceleration = change in angular velocity / change in time taken
Angular velocity = 635 rev/ min, covert to rad/ sec
The frequency in radians per second is equal to the revolutions per minute multiplied by 0.10472
Then angular velocity in rad/sec = 635 * 0.10472 = 66. 4972 rad/sec
time = 8. 0s
Substitute into the formula
Angular acceleration = 66. 4972 / 8. 0
Angular acceleration = 531. 98 rad/s²
Thus, the angular acceleration is 531. 98 rad/s²
