1.) The position of a softball thrown vertically upward is given by y = 7t – 4.9t2where y is in meters and t is in seconds. Find a) the initial speed of the ball at t=0, b) the velocity at t=1.26 s, and c) the acceleration of the ball.
2.) Starting from rest, an automatic subway train is controlled by a computer that causes it’s motion to follow the equation x = At3 for the first five seconds where x is the distance covered. Find expressions for expressions for the speed and acceleration as functions of time. If starting from rest, the train acquires a speed of 4 m/s in 5 s, what is the value of A including units
