Physics

An object of mass m1 = 0.435 kgstarts 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 0.395. Aftersliding down a distance d = 5.60 m, it makes a perfectly inelasticcollision with an object of mass m2 =0.650 kg at point .

a) Find the speed of m1 at point  justbefore the collision.

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

(c) After the collision, the objects travel on a horizontalsurface with a kinetic coefficient of 0.405. How long does it takeuntil the objects come to rest at point ?.
