Force and Laws of Motion

Impulse has the S.I. unit of ________.

A : Atheletes fall on a cushion in a high jump event to avoid getting hurt.
B : Time to come to rest is increased to reduce the force.

A : Force can change the direction and magnitude of the velocity.
B : Acceleration may be acquired due to the reduction in the mass of the body under motion.
C : Two masses moving with the same velocity can be stopped in distances S1 and S2 (< S1) such that m1 > m2 with the same retarding force.

A : The ratio of the S.I. to C.G.S. unit of forces is 105.
B : Water evolving out of a hose exerts no force on the pipe.
