Question 1
Given mass m = 0.6 kg and momentum p = 3.1 kg m/s
We have, Momentum = mass * velocity
p = m * v
Therefore, velocity, v = p / m
v = 3.1 / 0.6
v = 5.2 m/s
Answer is option c.
Question 2
Given mass m = 0.6 kg and momentum p = 3.1 kg m/s
Kinetic energy just before striking the floor
By conservation of mechanical energy,
Potential energy at height h = Kinetic energy just before striking the floor
Therefore , height from which it is dropped is
Answer is option c.
Question 3
Conservation of linear momentum can be applied when there is no external force acting on the body. Therefore, in the absence of an external force, a body's linear momentum remains a constant.
Answer is option b.
Question 4 and Question 5 cannot be done as their figures and graphs are not given
Question 6
During a collision, the kinetic energy is conserved when there is no deformation of the bodies or when they do not stick together after collision, that is, kinetic energy is conserved only if it is an elastic collision
Answer is option d
