Question

PROJECTILE MOTION PROBLEM:If you drop an object from a height of 1.5m, it will hit the ground in 0.55 seconds. If a baseball pitcher throws a baseball horizontally with an initial speed of 35 m/s from the same height: 1. How long will the ball take to hit the ground? 2. Where will the baseball land relative to the feet of the pitcher?

Answer 1

Answer:

a) $t=0.55sec$

b) $d=19.25m$

Explanation:

From the question we are told that:

Height $h=1.5m$

Time$t=0.55 seconds$

Speed $V=30m/s$

a)

Generally the Newtons equation for the time taken to hit the ground is mathematically given by

$s=\frac{1}{2}gt^2$

$t=\sqrt{\frac{2s}{g}}$

$t=\sqrt{\frac{2(1.5)}{9.81}}$

$t=0.55sec$

b)

Generally the equation for distance traveled is mathematically given by

$d=speed*time$

$d=35*0.55$

$d=19.25m$
