Answer 1

Complete Question

1-pound ball and a 100-pound ball are dropped from a height of 10 feet at the same time. In the absence of air resistance,

a the two balls end in a tie

b the 100-pound ball hits the ground first

c the 1-pound ball hits the ground first

d There's not enough information to determine which ball hits the ground first

Answer:

Option A

Explanation:

From the question we are told that:

Ball 1's Mass
`m_1=1lbs`

Ball 2's Mass
`m_2=100lbs`

Height
`H=10ft`

With Equal Gravitational acceleration of

`g=9.8m/s^2=32ft/s^2`

Generally the equation for Kinematics is mathematically given by

`S=Ut+(1)/(2)gt^2`

Since

`u=o,`

`g_1=g_2` and

Distance S traveled equal

`S_1=S_2`

Therefore

`T_1=T_2`

Hence "the two balls end in a tie"

Option A
