Answer:

A) x = -1/4

Step-by-step explanation:

There are 4 x's, 4 1's on one side of the equation, and 3 1's on the other side

4x + 4 = 3

Subtract 4 on both sides

4x = -1

Divide each side by 4

x = -1/4

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, ___
AysviL [449]

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
