What is the force of an object
from 15 m/s to 55 m/s in 10 seconds
a mass of 175kg?

700N

Explanation:

From the question, we obtained the following information:

M = 175kg

V = 55 m/s

U = 15 m/s

t = 10secs

To find the force, we must obtain the Acceleration of the object. The acceleration is obtained by:

a = (V — U) / t

a = (55 —15) / 10 = 40/10 = 4m/s2

Next, we find the force.This is done by

F = Ma

Where

M = 175kg

a = 4m/s2

F = Ma = 175 x 4 = 700N

hey there!

mass = 6.75 g

volume =   9 cm³

therefore:

d = mass / volume

d   = 6.75 / 9

d = 0.7 g/cm³
