1.Cheetahscan reach 20 m/s in 2.0 s starting from rest. Assuming that they have constant acceleration throughout that time, find:a)Theaccelerationb)The distance they travel during that time2.A block is given an initial velocity of 3.00 m/s up a frictionless incline of angle 20 degrees. How far up the incline does the block slide?3.A flea can jump straight up to a height of 22.0 cm.a)What is its initial speed (in m/s) as it leaves the ground, neglecting air resistance?b)How long is it in the air?c)What is the magnitude and direction of theacceleration of theflea when it is moving upward?d)What is the magnitude and direction of the acceleration when the fleait is at its highest point?e)What is the magnitude and direction of the acceleration when the fleais moving downward?4.A kid is playing with a toy car. Hepushes the car for a while at constant velocity, then lets goof the car. After he lets go, the car gradually comes to a stop because of friction. Sketch the position, velocity, and acceleration of the car as a function of time.
