Question

A cycle and truck both are moving with the same speed 40 km/h, both apply the brake and come to rest. which statement is true
1]Both have different initial momentum and different final momentum
2]Both have the same final momentum but the different initial momentum.
3]Both have the same initial momentum and the same final momentum. 4]Both have the same initial momentum but different final momentum

Answer 1

Answer:

The first semester of an undergraduate physics course invariably spends a lot of time on two big ideas: The momentum principle and the work energy principle. Both deal with forces acting on an object, which often leads students to think they are similar. In a way, they are, and they play a huge role in almost everything you learn during an introduction to physics.

Before I give you a great physics question that uses these ideas, I will go over them in a super-brief physics lesson. First, the momentum principle says that a net force changes the momentum of an object where the momentum is the product of mass and velocity. Working in one dimension to avoid dealing with vectors, I can write it like this:
