A block of mass 1.58 kg which is initially at rest is acted upon by an impulse of 8.22 Ns due to a constant force. The impulse lasts for 0.187 s seconds and results in the mass moving at velocity v. The block then slides up a frictional ramp which has a length 2.00 m and a height 34.8 cm before colliding with a mass 3.16 kg . In this problem all horizontal surfaces are frictionless (only the incline is frictional). A) With what velocity does the mass move after the impulse acts upon it? v = m/s
B) What average force acts upon the mass during the impulse? Favg = N
C) If the block reaches the top of the incline with velocity 3.91 m/s , what is the coefficient of kinetic friction of the ramp? μκ =
D) If the 1.58 kg block collides and sticks to the 3.16 kg block, what final velocity results? Vfinal = m/s
E) How much Kinetic Energy was lost in the collision of the two blocks? KElost = ___ J
