- What is the power done by gravity to make a ball of mass 0.68 kg roll from 1.3 m above the ground to the bottom along a curved path if it takes 2.68s to do so?Mac lifts a barbell up over his head the length of his arms. The barbell has a mass of 35 kg. If the length of his arms is relative to his shoulders is 71 cm, how much power does will Mac generate in lifting the barbell in 3 seconds?A ball with an initial velocity of 10 m/s rolls along a curved surface, as shown in the diagram. The mass of the ball is 100 g. Assume that the only energy conversions that take place are between the kinetic energy and the gravitational potential energy of the ball and calculate the speed of the ball at different positions v1, v2, v3, V4. 10 m/s U3 25 m 20 m 10 m 15 m
- Describe the energy transformations involved when a yo-yo is thrown downward and then climbs back up its string to be caught in the user’s hand.All of the following are TRUE regarding levers EXCEPT O a lever can increase the effect of force application to a body O a lever can increase the speed with which a body can be moved O a lever can increase the distance through which a body can be moved in a given time O the effect a lever has is dependent upon the location of the fulcrum, resistance, and the force in relation to each other. O all of the above are true
