An object of mass

m1 = 0.415 kg

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

θ = 36.0°

with the horizontal as shown. The coefficient of kinetic friction between the object and the incline surface is 0.455. After sliding down a distance d = 5.80 m, it makes a perfectly inelastic collision 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 the magnitude.

J

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

A box of mass m1 = 2.0 kg starts from rest and slides down the frictionless incline. At point A, the box encounters a (massless) spring of spring constant k. It compresses the spring a distance x = 0.25 m to point B where the speed of the box is 4.4 m/s. The first box is then removed and a second box of mass m2 = 3.0 kg is placed on the same incline at the same initial point and...

Beginning from rest, an object of mass 200 kg slides down a 9-m-long ramp. The ramp is inclined at an angle of 20o from the horizontal. Air resistance and friction between the object and the ramp are negligible. Let g = 9.81 m/s2. Determine the kinetic energy of the object, in kJ, and the velocity of the object, in m/s, at the bottom of the ramp.
