Answer:
Balanced forces
Explanation:
Balanced forces are where two forces of equal size act on an object in opposite directions. It means that in each direction, any pushes and pulls are balanced by another force in the opposite direction.
Explanation:
Below is an attachment containing the solution.
Answer:
Explanation:
Force - frictional Force = m * a
20N - 5N = 5 * a
15N = 5*a
15N / 5 = a
a = 3 m/s^2
You should note a couple of things.
1. The frictional Force always opposes the direction of motion. In this case it is minus and the 20 N is plus. It makes the acceleration less. If the friction force was not there then 20 N = m * a
20N = 5 kg * a
a = 20/5
a = 4 m/s^2.
Answer:
Given:
Mass = 20 kg
Acceleration = 2.5 m/s²
Explanation:
Force = mass × acceleration
= 20 × 2.5
= 50 kg m/s² or 50 N
