Sam, whose mass is 75\;kg, takesoff across level snow on his jet-powered skis. The skis have athrust of 200\;N and acoefficient of kinetic friction on snow of 0.1.Unfortunately, the skis run out of fuel after only 10\;s.
a) What is Sam's top speed?
b) How far has Sam traveled when he finally coasts to a stop?
At 2500K hydrogen gas (H2) adds two more degrees of freedom to its motion. It has three translation motions, two rotational motions, What would be its kinetic energy per molecule
Evangelista Torricelli was the first to put forward the idea that we live at the bottom of an ocean of air. (i) Given the value of the atmospheric pressure at the surface of the Earth.
As now ball which is thrown horizontally from the top of abuilding that is 11.0 m high lands 24.0 m from the base of thebuilding. How fas was the snowball travelling when it was thrown
Two balls of mud collide head-on in a perfect inelastic Collision. Suppose m1=0.5kg, m2 = 0.25kg, v1i = 4 m/s and V2i = -3 m/s, What is the change in kinetic energy in this collision
A piston contains 1 kg of argon gas at 300 K and 1 bar. The initial Volume occupied by the gas is 0.624 m3. Heat, in the amount 104.2 KJ, is added to elevate the temperature of the argon to 500 K while the pressure in the piston remains constant.
A batter hits a pitched ball when the center of the ball is 1.20 m above the ground. The ball leaves the bat at an angle of 45° with the ground. With that launch, the ball should have a horizontal range (returning to the launch level) of 107 m.
The safe slides with a constant speed if Clyde pushes from behind with 405 N of force while Bonnie pulls forward on a rope with 350 N of force. Illustrate what is the safe's coefficient of kinetic friction on the bank floor?
Three point charges are on the x-axis. The first is located at -4meters and has a charge of -6 coulombs. compute the net force on the charge at the origin
