An eskimo pushes a loaded sled with a mass of 300kg over the frictionless surface of hard-packed snow. he exerts a constant 170n force as he dose so. what is the sled's acceleration?

How are momentum and impulse related? impulse is a whim to do something, while momentum keeps it going impulse is another name fore instantaneous momentum the impulse acting on and object is equal to the change of momentum it causes. the impulse that acts on and object is the momentum that results.

The roller coaster from problem #1 then tops a second hill at 15.0 m/s, how high is the second hill? 91.5 m 79.2 m 80.0 m 68.5 m

Calculate the mass of an object that has a momentum of 100kg x m/sec and velocity of 4 m/sec
