Question

A block has a volume of 0.07 m3 and a density of 3,500 kg/m3. What's the force of gravity acting on the block (and weight) in the air?

Answer 1

The Correct answer to this question for Penn Foster Students is: 2401 N

Explanation:

Answer 2

W = mass * acceleration
and the gravity acceleration is know as 9.81 m/s^2
so we need to calculate the mass ,
from the givens , mass = density * volume
m= 3500*0.07 = 245 kg
subs. in W = m*g ,
W= 245 * 9.81
W = 2403.45 N
