A bucket of mass 1.90 kg is whirled in a vertical circle of radius 1.30 m. At the lowest point of its motion the tension in the rope supporting the bucket is 22.0 N.

A student (m = 73 kg) falls freely from rest and strikes the ground. During the collision with the ground, he comes to rest in a time of 0.04 s. The average force exerted on him by the ground is +18000 N, where the upward direction is taken to be the positive direction. From what height did the...

A 2.2-kg object is suspended from a spring with k = 18 N/m. The mass is pulled 0.35 m downward from its equilibrium position and allowed to oscillate. What is the maximum kinetic energy of the object?

A simple pendulum uses a steel wire as the string. The length of this wire is 4.02 m at room temperature. If the temperature of the pendulum increases by 25oC, what is the change in the period of the pendulum?

a baseball is thrown at an angle of 25 degrees relative to the ground at a speed of 23.0 m/s. If the ball was caught 42.0 m from the thrower,, how long was it in the air? How high was the tallest spot in the ball's path?

in a lab you submurge 100 g of 40 degree centigrade nails in 100 g of 20 degree centigrade water. tHE SPECIFIC HEAT OF IRON IS0.12 cal/g times degree centigrade. Equate the heat gained by the water to the heat lost by the nails and show that the final temperature of the water becomes 22.1...

An unknown volume of laughing gas has a temperature of 325 K and a pressure of 0.5 kPa. The temperature is decreased to 320 K, the pressure is increased to 1.2 kPa, and the final volume of the gas is 48.0 L. What was the initial volume of the laughing gas?

Please take a look at this question it has four parts. Thanks

Block A in the figure weighs 1.90 and block weighs 3.70. The coefficient of kinetic friction between all surfaces is 0.300.

Please answer this three part question Thanks
