Anita knows that she is one of the best basketball players on her team. Several colleges have been interested in recruiting her. One has offered her the opportunity to work with a specialist in biometrics once she joins the team. Anita does not think that this is really necessary since she is already a very skilled athlete. What is the BEST advice to give Anita?
A.
If everyone else on the team is doing it, she probably should too.
B.
Even the most skilled athletes can benefit from attention to biometrics.
C.
Using biometrics will help with her overall fitness but probably not her game.
D.
She probably already has all of the necessary skills since colleges are scouting her.

The average speed will be 2.38×10⁶ m/sec.The average speed of an object indicates the pace at which it will traverse a distance. The metric unit of speed is the meter per second.

The total distance traveled by an object divided by the total time taken is the average speed.

The speed calculated at any particular instant of time is known as the instantaneous speed.

Given data;

Distance travelled = 4.12x10¹⁶ meter

Time period= 1.73x10¹⁰ sec

The average speed is found as

[tex]\rm V_{avg}= \frac{d}{t} \\\\\ \rm V_{avg}= \frac{4.12 \times 10^{16}}{1.73 \times 10^{10} } \\\\\ V_{avg}=2.38 \times 10^6 \ m/sec[/tex]

Hence, the average speed will be 2.38×10⁶ m/sec.

Answer:

Correct option is A)

Weight on earth = 600N

Let g= 10m/s2 on earth

Mass on earth = 10600=60 kg

Now, since mass is a constant quantity so, it will remain 60 kg on the moon also.

Now, weight on moon = mg′

m= mass =60 kg

g′ = acc. due to gravity on moon = 61th the value on earth

So, Weight on moon = 61th of the weight on earth 

⇒ Weight on the moon =600×61=100 N

If both objects reach the same height, the ratio of their velocities Va and Vb is 3:1. The correct option is A.

When an object is thrown at an angle from the horizontal direction, the object is said to be in projectile motion. The object which follows the projectile motion.

Objects A and B have been projected from the same point at angles 30° and 60° with the ground, respectively. If both objects reach the same height.

The maximum height of the objects A and B are same, so

H = Va² sin²30 / 2g =  Vb² sin²60 / 2g

Va²/Vb² = sin²60/ sin²30

Va/Vb = 3:1

Thus, the correct option is A.

The acceleration of the car is 1.66 m per sec square.

The rate at which an item changes its velocity is known as acceleration, a vector quantity. If an object's velocity is changing, it is accelerating.

Initial velocity=0

Final velocity= 60km/hr

To convert it into m/sec

1 km=1000 m

1 hr=3600 sec

So= (60×1000)÷3600=16.66 m/sec

time=10 sec

We know that acceleration is the rate of change of velocity per unit of time.

acceleration=(final velocity-initial velocity)÷ time taken

                     = (16.66-0)÷10

                     = 1.66 m per sec square

So, Acceleration will be, 1.66 m per sec square

The initial velocity and the height of this building are 29 m/s and 780 meters respectively.

In order to calculate the initial velocity, we would apply the second equation of motion:

S = ut - ½at²

200 = u10 - ½(9.8 × 10²)

200 = u10 - 490

u10 = 490 - 200

u10 = 290

u = 290/10

Initial velocity, u = 29 m/s.

Next, we would determine the height of the building:

H = ut + ½at²

H = 29(10) + ½(9.8 × 10²)

H = 290 + 490

Height, H = 780 meters.

The velocity of the ball going when it reaches the base of the hill will be 5.5 m/sec.

The change of distance concerning time is defined as speed. Speed is a scalar quantity. It is a time-based component. Its unit is m/sec.

The complete question is;

A 10 kg ball is released from the top of a hill. How fast is the ball going when it reaches the base of the hill? Approximate g as 10 m/s2 and round the answer to the nearest tenth.

hy = 2 m

h = 0.5 m

The given data in the problem is

m is the mass of block =  10 Kg

u is the initial velocity of fall = 0 m/sec

h is the distance of fall =  2.5 m

g is the acceleration of free fall =10 m/sec²

v is the hitting velocity of =?

According to Newton's third equation of motion;

[tex]\rm v^2=u^2+2g(h_2-h_1) \\\\ \rm v^2=0+2g(h_2-h_1) \\\\ v = \sqrt{2g(h_2-h_1)}\\\\ v = \sqrt{2 \times 9.81 \times (2-0.5)|}\\\\ v =\sqrt{2 \times 9.81 \times 1.5 } \\\\ v = 5.5 \ m/sec[/tex]

The centripetal acceleration of the tip of the fan blade is 96.23 m/s²

The acceleration developed when a body is moving in circular way, directed towards the center of the circular path.

The tip of a fan blade is 0.61 m from the center of the fan. the fan turns at a constant speed and completes 2 rotations every 1.0 s

ac = ω²r

where ω = angular speed = 2πN/60, N = Rotation per minute

From the question, N = 2 x 60/1 = 120  RPM

So, the angular speed will be

ω = 2π x 120 /60

ω  = 12.56 rad/s

Then, the centripetal acceleration is

ac =  (12.56)² x   0.61 m

ac = 96.23 m/s²

Thus, centripetal acceleration of the tip of the fan blade is 96.23 m/s²
