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

Asilver dollar is dropped from the top of a building that is 1324 feet tall. use the position function below for free-falling objects. s(t) = −16t2 + v0t + s0 (a) determine the position and velocity functions for the coin. s(t) = v(t) = (b) determine the average velocity on the interval [1, 2]. ft/s (c) find the instantaneous velocities when t = 1 second and t = 2 seconds. v(1) = ft/s v(2) = ft/s (d) find the time required for the coin to reach the ground level. (round your answer to three decimal places.) t = s (e) find the velocity of the coin at impact. (round your answer to three decimal places.) ft/s
