Question

Ted Williams drops a ball from 12.7 meter to a desk that is 1.5 meter tall. What is the final speed of the ball right before it hits the desk?

Answer 1

Step-by-step explanation:

Using the equation of motion

V² = u²+2g∆H

v is the final velocity

u is the initial velocity = 0m/s

g = 9.8m/s²

∆H = 12.7-1.5 = 11.2m

Substitute

v² =0²+2(9.8)(11.2)

v² = 219.52

v = √219.52

v = 14.82m/s

Hence the final.speed of the ball is 14.82m/s
