Question

1. State Newton's 2nd law of motion along with 3 examples.
2. Calculate the force acting on a body of mass 51 kg when it is accelerated by 0.8 m/s^2​

Answer 1

Answer:

Newton's Second Law

Newton's Second Law of Motion says that acceleration (gaining speed) happens when a force acts on a mass (object). Riding your bicycle is a good example of this law of motion at work. ... Your leg muscles pushing pushing on the pedals of your bicycle is the force. When you push on the pedals, your bicycle accelerates.

Newton's Third Law

His third law states that for every action (force) in nature there is an equal and opposite reaction. In other words, if object A exerts a force on object B, then object B also exerts an equal and opposite force on object A.

The force of gravity pulling you down against your chair is balanced by the force of the chair pushing up against you. The forces acting on you as you sit in your chair are just one example of Newton's third law, which states that for every action force there is an equal and opposite reaction force.

2)Calculate the force acting on a body of mass 51 kg when it is accelerated by 0.8 m/s^2

Given: Mass = 51 kg

Acceleration = 0.8 m/s²

Ans:

Force applied will me

F = mass x acceleration

= 51 x 0.8

= 40.08 N
