c) momentum of the particle constant
b) particle going along a straight line
d) acceleration of the particle constant
of a hody
[​

Answer 1

Answer:

particle going along a straight line. C ... acceleration of the particle is constant ... If the rate of change in momentum is zero or momentum is constant then net force ... Race car A follows path abcde while race car B follows path 12C34 rack if each car ... In order to keep a body moving in a circle, there exists a force on it that is ..

Explanation:

Answer 2

Answer:

momentum of the particle constant

Explanation:

If the rate of change in momentum is zero or momentum is constant then net force acting on the body is zero
