Question

_______. A 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, __________. the 100-pound ball hits the ground first the 1-pound ball hits the ground first the two balls end in a tie There's not enough information to determine which ball hits the ground first

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

Step-by-step 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

$S=Ut+\frac{1}{2}gt^2$

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
