A 60.0 kg skier starts from rest at the top of a 1500.0 m long trail which drops a total of 230.0 m from top to bottom. At the bottom, the skier is moving 12.0 m/s. Calculate the energy dissipated by friction. [Given coefficient of kinetic friction of snow = 0.03]

A man on a motorcycle plans to make a jump as shown in the figure. If he leaves the ramp with a speed of 30.0 m/s and has a speed of 28.4 m/s at the top of his trajectory, determine his maximum height (h) (in m) above the end of the ramp. Ignore friction and air resistance. ורו

A 52 kg skier starts from rest at height H = 17 m above the end of a ski-jump ramp (see the figure). As the skier leaves the ramp, his velocity makes an angle of 0 = 25° with the horizontal. Neglect the effects of air resistance and assume the ramp is frictionless. (a) What is the maximum height h of his jump above the end of the ramp? (b) If he increased his weight by putting on a 10 kg backpack, what would h be? End of H ramp (a) Number i Units (b) Number i Units >

A luggage handler pulls a 15 kg suitcase up a ramp inclined at an angle 33⁰ above the horizontal by a horizontal force F of magnitude 180 N. The coefficient of kinetic friction between the ramp and the suitcase is 0.35. If the suitcase travels 1.6 m along the ramp, calculate  (e) If the package started from rest, what is its speed after it has travelled 1.6 m?

angle e = 30° onto the rough surface having a coefficient of kinetic friction PK = 0.2. Neglect the size of the package. How long will it take for the package to stop considering only its movement on the horizontal ground? The package of mass M = 5 kg is released from rest at A which is h = 3 m above the ground. It slides down the frictionless plane which is inclined at an O 3.91s O 1.965 O 0.90s O 4.51s

A drone at too great a height drops a box. The box drops straight down the ground and hits at 100 m/s smashing the contents. Neglecting air friction, approximately, how high, in m, was the drone? O 360 O 720 O 250 O 510 O 25

John reached a speed of 29 m/s in the downhillskiing competition. Suppose he left the slope at that speed andthen slid freely along a horizontal surface. If the coefficient ofkinetic friction between his feet and the ground was 0.27 andhis final speed was half of his initial speed, find the distance hetraveled.

A 1.5-kg box is released from rest on a frictionless surface that is sloped at θ = 35◦ above the horizontal.After sliding 1.0 m down the slope, the box transitions smoothly to a rough, horizontal surface, slides forsome distance, and then comes to a stop. If the coefcient of kinetic friction between the box and thehorizontal surface is 0.12, how far along the horizontal surface does the box travel?
