Part -1:

The position of a softball tossed vertically upward is described by the equation

y = t - C² - t²,

where y is in meters, t in seconds, e = 7.6 m/s, and c2 = 5.62 m/s².

Find the ball's initial speed v_o at to = 0s. Answer in units of m/s

Part -2:

Find its velocity at t = 1.06 s.

Part -3:

Find its acceleration at t = 1.06 s. Answer in units of m/s²

A ball is thrown straight up from the ground with an initial velocity of 39.2 m/s; at the same instant, a ball is dropped from the roof of a building 27.7 m high.

After how long will the balls be at the same height? The acceleration of gravity is 10 m/s².
