Question

If you drop an object from a height of 1.4 m, it will hit the ground in 0.53 s. If you throw a baseball horizontally with an initial speed of 35 m/s from the same height, how long will it take the ball to hit the ground?

Answer 1

The ball to hit the ground in 0.53 s.

Step-by-step explanation:

Given that,

Height = 1.4 m

Time t = 0.53 s

Initial speed = 35 m/s

We need to calculate the time when the ball to hit the ground

Using equation of motion

`s_(y)=u_(y)t-(1)/(2)gt^2+h_(0)`

Where, s= vertical height

u= vertical velocity

t = time

h = height

Put the value in equation

`0=0-(1)/(2)*9.8* t^2+1.4`

`t^2=(1.4)/(4.9)`

`t=\sqrt{(1.4)/(4.9)}`

`t=0.53\ s`

Hence, The ball to hit the ground in 0.53 s.
