An object is attached to a light string and is forced to move in uniform circular motion on a frictionless table. The radius of the circular path is 0.5m and the maximum amount of tension the rope can withstand without breaking is 16N. What is the maximum amount of kinetic energy this object can have?

Justin, with a mass of 50 kg, is going down an 8.0-m-high water slide. He starts at rest, and his speed at the bottom is 12 m/s. How much thermal energy is created by friction during his descent? Eth=

A running 50-kg cheetah has a top speed of 30 m/s. (a) What is the cheetah's maximum kinetic energy? ____J (b) Find the cheetah's speed when its kinetic energy is one half of the value found in part (a). ____m/s

A block is sent up a frictionless ramp along which an x axis extends upward. The figure gives the kinetic energy of the block as a function of position x; the scale of the figure's vertical axis is set by Ks = 44.0 J. If the block's initial speed is 5.00 m/s, what is the normal force on the block?

For its size, the commonflea is one of the most accomplished jumpers in the animal world.A 2.0-mm-long, 0.50 mg flea can reach a height of 20 cm in a singleleap. Most humans can jump no more than 60 cm from a crouched start. What is the kinetic energy per kilogram of mass at takeoff for such a 65 kg person?

Please answer and solve the question correctly. Thank you!

The largest watermelon ever grown had a mass of 118 kg. Suppose this watermelon were exhibited on a platform 5.00 m above the ground. After the exhibition, the watermelon is allowed to slide along to the ground along a smooth ramp. How high above the ground is the watermelon at the moment its kinetic energy is 4.61 kJ?

A furniture carrier pushes a 60 kg crate with a constant velocity v = 2.0 m/s on a rough inclined plane with a height of 1.0 m and a length of 2.0 m with a coefficient of kinetic friction uk = 0.30. What is the amount of change in potential energy of the crate?

A sprinter who weighs 639 N runs the first 8.6 m of a race in 1.9 s, starting from rest and accelerating uniformly. What are the sprinter's (a)speed and (b) kinetic energy at the end of the 1.9 s? (c) What average power does the sprinter generate during the 1.9 s interval?
