The mass of the second car is 1434.21 kg
<u>Explanation:</u>
Using law of conservation of momentum,

Given:
= 1090 kg
= 11 m/s
= 0
v = 4.75 m/s
We need to find 
When substituting the given values in the above equation, we get





1. pulling tug of war
2. monkey swinging from vine
3. arm wrestle
It will help them stay in better shape resulting in better health, being more physically active, and staying happier as a result.
The frictional force while the mass is sliding will be 46.2 N.
<h3>What is friction force?</h3>
Opposition forces on the surface cause heat loss during the motion of an object known as the friction force.
Given data:
m(mass)= 10.0-kg
Θ (Inclination angle)=25.0o
Coefficient of sliding friction,
=0.520
Coefficient of static friction,
The friction force, F=?
Resolve the force in the inclined plane;

Hence, the frictional force while the mass is sliding will be 46.2 N.
