Question

To celebrate a victory, a pitcher throws her glove straight upward with an initial speed of 5.2 m/s. How long does it take for the glove to reach its maximum height

Answer 1

The glove will take 0.52s to reach the maximum height.

Step-by-step explanation:

Here, we will use Newton's first equation of motion,

v = u +at

where v= = final speed, u = initial speed, a=acceralation, and t is time.

We have given u=5.2m/s, and we know that the deacceleration produced in the body is equal to the acceleration due to gravity, g=9.8m/s. When the object reaches maximum height, its speed will be zero at that instant, v=0.

substituting the values

0 = 5.2 + (-9.8)t

solving for t, we get t = 0.52s.
