A baseball pitcher throws a baseball with a speed of 36 m/sm/s . In throwing the baseball, the pitcher accelerates it through a displacement of about 3.5 mm, from behind the body to the point where it is released. Estimate the average acceleration of the ball during the throwing motion.

A person stands on a cliff edge and throws a stone vertically upwards at time t = 0. The stone leaves their hand at 20 m/s. Take the acceleration due to gravity as 9.8 m/s Calculate the height of the stone 2.0 s after release and 6.0 s after it is released.

14. The speed of a nerve impulse in the human body is about 100 m/s. If you accidentally stub you toe in the dark, estimate the time it takes the nerve impulse to travel to your brain. (Assume that you are approximately 1.70 m tall and that the nerve impulse travels at uniform speed.)

An object is initially at rest and subject to a constant acceleration of 2.17 m/s2. What amount of time will it take this object to undergo a displacement of 26.3 from its initial position

Two cars are leading toward one another. Car A is moving with an acceleration of a = 4 m/s² i. Car B is moving with a constant acceleration ab = -2 m/s2 i and initial velocity of VB = -60 m/s i since it started. The cars are initially separated by a distance d = 900 m on the x-axis and car A is initially at rest. At what distance from the initial position of A do car A and car B meet? A. 200 m B. 400 m C. 300 m D. 500 m E. 600 m ΟΑ OB OC OD SOE K
