A ball is thrown vertically upward with a speed of 12.0 m/s.

(a) How high does it rise?

Expert Answer

Step 1

Given data :

Initial velocity ,u 12m/s When the ball reaches the maximum height, its velocity becomes zero. Thus, Final velocity, v 0 Acceleration will be downwards due to gravity. Thus, acceleration, = -9.81 m/s2

Step 2

Now, we know ...

v2 -u22as or, 0 (12)2 2(-9.81)s -144 7.34 m or,s -2 x 9.81
