A hockey player uses a 400-gram stick to apply 50 newtons of force to a 170-gram puck, causing a momentum change of 5 kg•m/s.
What is the impulse experienced by the hockey puck?

A. 5 N•S
B. 8N•S
C. 10N•S
D. 50N•S

please hell!!

Ablock having mass m slides down an inclined plane. the force of friction between the block and the inclined plane is f, the block's weight is m g, and the normal force is n. (a) draw a free – body force diagram showing the forces acting on the block. (b) write down all relevant newton’s equations for a given situation.
