The force is the same and the time in the same; therefore, the impulse on each object is the same.

Homework Statement In a collision between two unequal masses, how does the impulse imparted to the smaller mass by the larger mass compare with the impulse imparted to the larger mass by the smaller one? A) It is smaller. B) The answer depends on how fast they are moving. C) They are...

I used \frac{tan21.8}{515} to find it, not Fsinθ.

I found the y component of the applied force and then added that to the normal force of the crate on the plane.

I got practically the same answer.

1. A 250-kg crate rests on a surface that is inclined above the horizontal at an angle of 21.8°. A horizontal force (magnitude = 515 N and parallel to the ground, not the incline) is required to start the crate moving down the incline. What is the coefficient of static friction between the crate...
