Question

Physics

An object of mass

m1 = 0.415 kg

starts from rest at point  and slides down an inclinesurface that makes an angle

θ = 36.0°

with the horizontal as shown. The coefficient of kineticfriction between the object and the incline surface is 0.455. Aftersliding down a distance d = 5.80 m, it makes a perfectly inelasticcollision with an object of mass

m2 = 0.645 kg

at point .

(a) Find the speed of

m1

at point  just before the collision m/s

(b) Find the energy loss during the collision. Enter themagnitude.

J

(c) After the collision, the objects travel on a horizontalsurface with a kinetic coefficient of 0.455. How long does it takeuntil the objects come to rest at point ?.
