A 1.5 kg ball is thrown directly downward with an initial velocity of 13 mfs from a height of 25 m. If the velocity of the ball is 24 mfs at ground level, how much energy is lost due to air resistance? A 40 kg sled is pulled across a horizontal surface a distance of 3D rn by a 25G N force angled 3?\" above the horizontal. If the coefficient of kinetic friction between the sled and the surface is 21.15, what is the net work done to the sled? How much work is being done by friction for a 2.5 kg block to slide 1.3 m down a 45 incline in 1190 s after starting from rest? A 50 kg circus performer dives from a height of 3.5 m into a bucket of water 0.25 m tall. What force must the water exert on the performer in order for her to stop before the bottom of the bucket? A 3.5 kg block is pushed into a horizontal spring along a frictionless surface. Ifthe spring constant of the horizontal spring is 15G mm, and the block is pushed {1?5 m into the spring, to what height would the block travel up an incline when released from the spring? A 10D kg washing machine is being placed into a second story apartment located 3.1 m above the ground. a. How much work is being done to raise it into the apartment at a constant velocity? b. How much work would be done if a frictionless 3G\" incline were used instead? c. Calculate the force required to push the washing machine up the incline in part b at a constant velocity. Each second, 120!) m3 of water passes over a waterfall 1G0 rn high. Three-fourths of the kinetic energy gained by the water in falling is transferred to electrical energy by a hydroelectric generator. How much power does the generator produce as electrical energy? [The mass of 1 m3 of water is l kg.} A 11342 kg cart rolls down an inclined ramp. The initial height of the cart is 0.53 m above the surface ofa table. If the speed of the cart is 2.15 mfs when it is 0.23 m above the surface ofthe table, how much energy has been lost to friction during the run
