When considering gravity acceleration and the force of acceleration, Option C. The direction of the force and the direction of acceleration must be the same as each other.
Acceleration is the rate of change of the velocity of an item with appreciation to time. Accelerations are vector portions. The orientation of an item's acceleration is given by the orientation of the net pressure appearing on that object.
Acceleration is the charge at which velocity modifications with time, in terms of each speed and route.

a 22.0 kg crate is initially moving with a velocity of 3.90 m/s in a direction 440 west of north. how much work must be done on the crate to change its velocity to 6.67 m/s in a direction 63.00 south of east? do not include units.
The crate needs to put in 1000.63 Joule of work in order to shift its velocity from 0 to 6.67 m/s in the direction of 63.00 south-east.
What work is being done?We are aware that the definition of labor is the multiplication of the force operating in the direction of the displacement (d) and its component.
Given,
A 22 kg container is initially traveling 440 degrees west of north at a speed of 3.90 m/s.
the cosine formula was used to compute the outcome velocity.
where angle ∅ = 440 + 90 + 63 = 593°
v² = (3.90)²+(6.67)² - 2(3.9)(6.67) cos 593
v² = 59.6989 + 52.026 × 0.601
v² = 59.6989 + 31.2676
v² = 90.9665
Resultant velocity V = 9.5376
V = 9.53 m/s
To calculate the much work that must be done on the crate to change its velocity to 6.67 m/s in a direction 63.0° south of east, Because energy and labor are equivalent, the kinetic energy formula is used.
W = 1/2mv²
Where,
m = 22 kg and
v = resultant velocity = 9.53 m/s

Average force skater had experienced without breaking a bone is 3,082 N. if the impact time is 0.115 s then the average force a skater experience is increased by 3423 N and yes, the bone breaks.
What is Average force?The vector quantity of a force. It is a quantity with both magnitude and direction, hence. We must specify both the size and the direction of the force operating on an object in order to adequately understand it. The average force is force applied by an item travel over specific period of time at a given rate of speed, or velocity.
Given,
m₁ = 75 kg
u₁ = 10.5 m/s
V = 5.52 m/s

the speed of raindrop (v) = 8.1 m/s
putting all values in above formula we get,
J = mv = 0.014×10⁻³ × 8.1 = 0.013 × 10⁻³ kg m/s
thus, value of impluse is 0.013×10⁻³3 kg m/s
b) Average force of impact is defind as the product of mass of object by the average velocity of object over a definite time.
According to Newton's Second law of motion,
force (F) = m× a
where m---> mass of object
a----> acceleration which is equal to change in velocity with respect to time.
Now, we have given m = 0.014 ×10⁻³3 kg
time = 0.37 ms
acceleration (a) = v/t = ( 8.1 m/s )/ 0.37 ms
putting all values in above formula we get,
force = (0.014×10⁻³kg × 8.1 m/s )/0.37 ×10⁻³ s
= 0.306N ~ 0.31N
Thus, magnitude of average force of impact is 0.31 N .

an eccentric hollywood movie producer, vacationing in australia, goes to an observatory and offers to make a big donation if they can show him a place in the milky way galaxy where there are more than a million stars seen together. which object would satisfy his extravagant tastes?
The object that would satisfy his extravagant tastes, The globular cluster Omega Centauri.
When the core temperature reaches about 100 million degrees helium begins to fuse into carbon through a reaction known as the triple-alpha process, converting three helium nuclei into one carbon atom. This creates a lot of heat. Red giants are dying stars in the final stages of stellar evolution.
In about 5 billion years, our Sun will transform into a red giant and expand to engulf the inner planets, possibly Earth. Stars entering the red giant stage are notorious for their rapid loss of mass. As noted above, the upper layer's gravity weakens and can be ejected into space by violent events such as the initiation of a helium flash within the core.
