QUESTION 6 A falling package with a parachute is greatly affected by air resistance. Suppose a package (m 25 kg), dropped from an altitude of y = 1500 m, hits the ground at a speed of v = 45 m/s. Calculate the work done by air resistance. By conservation of energy, the initial total mechanical energy is equal to the final total mechanical energy. Let K be the kinetic energy, U be the gravitational potential energy, and Wair be the work done by the drag force from air resistance.

1) Figure 2 illustrates a block having mass M positioned on a ramp having ramp angle 0 above the horizon. The contacting surfaces have a coefficient of kinetic friction, lk. The block is released from rest and it slides down the ramp such that the magnitude of its vertical displacement is H. The speed of the block when it reaches the bottom of the ramp is Vf. Determine expressions {Uk, 0, g, H, M} for the following: a) the work done on the block by friction; b) the work done on the block by the normal force; c) the work done on the block by gravity; and d) the final speed V¢ of the block M Figure 2 H

An 8.5-kg block is pushed along a horizontal rough surface by a 40-N force inclined at 20° with the horizontal. The coefficient of friction between the surface and block is 0.35. If the block has an initial velocity of 3.6 m/s and the force does 200 J of work on the block, find: Question: The final velocity of the block.
