Question

A truck with a mass of 2500 Kg travelling with an acceleration of 5 m/s^2 hits a scooter. What force does the truck experience?

(a) 12500 N

(b) 500 N

(c) 10000 N

(d) 2500 N

The question was posed to me in a national level competition.

My query is from Newton’s Third Law of Motion in section Laws of Motion of Physics – Class 11

Answer 1

Correct answer is (a) 12500 N

To explain: From Newton’ second law we get force on scooter = 2500 x 5 = 12500 N. From Newton’s third law we know that for every for every action, there is an equal and opposite reaction. From this we can say that the truck experiences a force of 5 N.
