An old miser with a bag og gold jums onto the surface of a frozen lake and hopes to coast civilization on the other side.Unfortunately the ice does have a coefficient of kinetic friction ?ₖ=0.08. He slides for 80 m and then stops.(Now he has to walk.) How fast was he moving at the start of his coast?

Please answer the question correctly. Thank you!!

A skier, starting from rest, moves from the top of a ramp to the bottom.  If the vertical drop is 3.12 meters, what is the speed in m/s of the skateboarder at the bottom of the ramp. (neglect friction). Can you help with a visual aid; and then, explain the mechanics of calculation.

A 66 kg Man pushes off the 87kg Block on ice and slide away at a speed of 3 m/s. What is the speed of the block?

previous problem:  A small block slides down a frictionless track whose shape is described by y = (x^2) /d for x<0 and by y = -(x^2)/d for x>0. The value of d is 3.85 m, and x and y are measured in meters as usual. Suppose the block starts from rest on the track, at x = -1.99 m. What will the block s speed be when it reaches x = 0?   New problem Same type of track as in the previous problem, this time with d = 4.73 m. The block starts at x = 0, and is given a push to the left with an initial speed of 7.57 m/s, so it starts sliding up the track to the left. At what value of x will the block reverse direction and start sliding back down?     -3.72 m     3.72 m     2.92 m     -2.92 m

A car goes down a 100 incline with a coefficient of friction of 0.3 for 1 m. What is it’s final velocity?

6. Two blocks are connected by a light string passing over a light, frictionless pulley as shown in the figure. Block m1, initially at rest, is released from height h above the table. Block m,, which is the heavier block, begins to fall, while block m2 rises. a) Calculate the speed of m2 just as m¡ hits the table. b) Suppose block m, continues to rise without obstruction even after block m, hits the table. Calculate the maximum height above the table to which m2 rises. h

help on this please!!

A 1,300kg car is traveling at a velocity of 30.0m/s when the driver slams on the brakes. If a constant force of kinetic friction of magnitude 9,200N acts on the car, how far does the car travel when it comes to a stop

A bowling ball is dropped from the top of a building that has a height of h = 112 m. Part (a)  Assuming air resistance is negligible, what is the ball's speed, vf in m/s, when it strikes the ground?Part (b)  If drag produces an opposing force of 10 N while the ball's falling, what is the ball's speed, vf in m/s, when it strikes the ground? Assume the ball has a mass of 5 kg.Part (c)  A different ball was dropped and the final speed was measured to be vf = 8.5 m/s while the drag force was measured to be 50 Newtons. What is the mass of this ball in kg?
