Problema Solution

A ball is tossed upward with a starting velocity of 10 ft/s from a height of 3ft. Substitute the values into the vertical motion formula. Let h=0.Solve. If it is not caught, how long will the ball be in the air? Round to the nearest tenth of a second.

The formula is

h = 3+10t- (1/2)(32)t^2

That is h = 3+10t- 16t^2

When h=0,

3+10t- 16t^2 = 0, t = 0.8

So when t=0.8 second, h=0
