4) A cheetah can accelerate from rest to 25.0 m/s in 6.22s. Assuming constant acceleration, (a) how far has the cheetah run in this time? (b) After sprinting for just 3.11s, is the cheetah’s speed 12.5 m/s, more than 12.5 m/s, or less than12.5 m/s? Explain. (c) What is the cheetah’s average speed for the first 3.11 s of its sprint? For the second 3.11s of its sprint? (d) Calculate the distance covered by the cheetah in the first 3.11 s and the second 3.11 s. 5)A hot air balloon is descending at a rate of 2.0 m/s when a passenger drops a camera. If the camera is 45 m above the ground when it is dropped, (a) how long does it take from the camera to reach the ground, and (b) what is the velocity just before it lands? Let upward be the positive direction for this problem.
