A) find the initial velocity of the ball. Answer in units of m/s^2 B) find the maximum height it reaches. Answer in units of m The acceleration of gravity is 9.8 m/s^2

Explanation / Answer

a) v=u+at

0=u+9.8*2.7

u=-26.46 m/sec

b)

x = x0 + v0(t) + 1/2 at^2

x = 0 -26.46*2.7 + 0.5*9.8*2.7*2.7

x=-71.442+

x =

x = x0 + v0(t) + 1/2 at^2

x = 0 + 0(6) + 34.3/2 * 36

x = 2931.79 m
