64. A certain quantity of steam has a temperature of 100.0 °C. To convertthis steam into ice at 0.0 °C, energy in the form of heat must be removedfrom the steam. If this amount of energy were used to accelerate the icefrom rest, what would be the linear speed of the ice? For comparison,bullet speeds of about 700 m/s are common.

The principle of conservation of energy indicates that, mLv+cm∆T+mLf=12mv2 Lv+c∆T+Lf=12v2

A 58-kg diver is standing on a platform that is 35 meters above the surface of the water. He steps off the platform with zero initial velocity and descends toward the water below. Assuming that no energy is lost to his surroundings, how much kinetic energy (in joules) does the diver have right before he hits the water?
What mass of butter, which has a usable energy content of 6.0 Cal/g (= 6000 cal/g), would be equivalent to the change in gravitational potential energy of a 87 kg man who climbs 5.41 km? Assume that the average g for the climb is 9.80 m/s². Number i Units
This time, the pendulum is 1.07 m long and has a mass of 3.19 kg. You give it a push away from vertical so that it starts swinging with a speed of 1.02 m/s. Due to friction at the pivot point, 1.00 Joule of the pendulum s initial kinetic energy is lost as heat during the upward swing. What maximum angle will it reach, with respect to the vertical, before falling back down? 18.1 degrees 20.5 degrees 19.3 degrees 11.4 degrees
Brad tries out a weight-loss plan that involves repeatedly lifting a 44.2-kg barbell from the floor over his head to a height of 2.00 m. If he is able to complete three such lifts per minute, how long will it take for him to lose 0.50 kg of fat? “Burning” 1 g of fat supplies 38.8 kJ to the body; of this, 10.0% can be used by the muscles to lift the barbell. (Ignore the fat “burned” while he lowers the barbell to the floor.)

6. A new event has been proposed for the Winter Olympics. As seen in the figure, an athlete will sprint 100 m, starting from rest, then leap onto a 20 kg bobsled. The person and bobsled will then slide down a 50-m-long ice-covered ramp, sloped at 20°, and into a spring with a carefully calibrated spring constant of 2000 N/m. The athlete who compresses the spring the farthest wins the gold medal. Lisa, whose mass is 40 kg, has been training for this event. She can reach a maximum speed of 12 m/s in the 100 m dash. 20° ww (a) How far will Lisa compress the spring? (b) The Olympic committee has very exact specifications about the shape and angle of the ramp. Is this necessary? What factors about the ramp are important?

5. A cart with m= 3.40kg rides on the track shown. The track is frictionless except for a level section 0.40m long where μk = 0.54. The cart is initially at rest against spring 1 (k₁ = 1400N/m) which is compressed by 8.00cm. When released it travels along the track until it reaches spring 2 (k2= 800N/m) which it compresses until the cart stops. If h₁ = 0.38m and h₂ = 0.14m, determine the speed of the cart at points A, B, C and D. Also how much will spring 2 be compressed at the end. framm] =3.40kg kží = 800 N/m Remb A k₁=1 2₁-1400/m h₁-0,38 D B d=0.40m = 0,54 мк of ....... oservation Im h₂= = 0,14
This time, the pendulum is 1.93 m long and has a mass of 3.17 kg. You give it a push away from vertical so that it starts swinging with a speed of 1.62 m/s. Due to friction at the pivot point, 1.00 Joule of the pendulum s initial kinetic energy is lost as heat during the upward swing. What maximum angle will it reach, with respect to the vertical, before falling back down? 18.7 degrees 21.5 degrees 31.8 degrees 26.7 degrees
