Question

Two object A and B having masses 100kg and 75kg moving with velocities 40km/h and60km/h respectively. answer the following a)which will have greater inertia. b)which will have greater momentum. c)which will stop first if equal negative acceleration is applied on both. d)which will travell greater distance in 10min e)which will impact greater force if collided with wall.

Answer 1

a. Object A as it is heavier.
b. A= 100×40=4000
B=75×60 =4500
So B has greater momentum
c. Object B as it has less inertia
d. Object B as it has greater momentum
e. Object B as it has greater momentum
