A sled and rider have a total mass of 50 kgs. If the sled is given an initial velocity of 10 m/s in the forward direction on a flat snowy road, then what is the distance traveled by this sled (with rider) before coming to a stop? The coefficient of kinetic friction between the sled and the snow is 0.2. Use g = 10 m/s2.

Answer #1

kinetic energy = energy lost in friction.


0.5mv2 = µmgd

0.5x100 = 0.2x9.8xd

d= 25.5 m

    Classes are canceled due to snow, so you take advantage of the extra time to conduct some physics experiments. You fasten a large toy rocket to the back of a sled and take the modified sled to a large, flat, snowy field. You ignite the rocket and observe that the sled accelerates from rest in the forward direction at a rate of 15.5 m/s2 for a time period of 2.90 s. After this time period, the rocket engine abruptly shuts...

    A sled is given a push across a horizontal surface. The sled has a mass m, the push gives it an initial speed of 3.10 m/s, and the coefficient of kinetic friction between the sled and the surface is 0.105. (a)Use energy considerations to find the distance (in m) the sled moves before it stops. m (b)What If? Determine the stopping distance (in m) for the sled if its initial speed is doubled to 6.20 m/s. m

    A sled and its passengers have a total weight of 400N. Once the sled starts to move, how much force would be required to overcome the friction between the wooden sled and the wet snow. The coefficient if static friction between the wood and the snow is 0.2 and the coefficient of kinetic friction is 0.13.

    A 51.9-kg person, running horizontally with a velocity of +3.43 m/s, jumps onto a 14.2-kg sled that is initially at rest. (a) Ignoring the effects of friction during the collision, find the velocity of the sled and person as they move away. (b) The sled and person coast 30.0 m on level snow before coming to rest. What is the coefficient of kinetic friction between the sled and the snow?
