The average acceleration of the cheetah is 7.75 m/s²
The given parameters;
velocity of the cheetah, v = 31 m/s
time of motion, t = 4 seconds
The average acceleration of the cheetah is calculated as follows;

where;
v is the final velocity
u is the initial velocity
t is the time of motion
Assuming the cheetah started from rest, the initial velocity, u = 0
The average acceleration is calculated as follows;

Thus, the average acceleration of the cheetah is 7.75 m/s²

Answer:
1.)The bob of pendulum should be displaced with a small angle.
2) The amplitude of the oscillation of a simple pendulum should be small.
3) Fans should be switched off to reduce the air resistance.
4)The simple pendulum should be oscillate in a vertical plane

Explanation:
As the Sun heats the ocean, the water evaporates, turning into a gas. Sometimes this gas meets cooler air, and the gas changes into drops of water. This process is called condensation. Drops of water fall back down to Earth again as precipitation, which can be in the form of rain, snow, sleet, or hail
three phases of water cycle are
evaporation, condensation, <em>precipitation</em>

First of all, we need to calculate the work done by the forklift to lift the box of 500 kg by 4 meters. The work done is equal to the variation of gravitational potential energy of the box, given by:

where m=500 kg is the mass of the box,

and

is the variation of height of the box. Substituting these data into the equation, we find the work

And now we can calculate the minimum power required by the forklift, which is equal to the ratio between the work done and the time taken:
