1. Gwendylla is riding on a sled while Ellawyn is pushing her up a hill. Ellawyn is pushing Gwendylla's sled from behind with a force of 60N at an angle of 35 degrees below the plane of the hill's surface. Gwendylla has a mass of 40kg , ellawyn has a mass of 50kg, and the seld has a mass of 20kg . A) draw a free body diagram fro Gwendylla on her sled. B) What is the acceleration of Gwendylla...

Imagine that you're sledding alone down a steep hill on a toboggan and that you left the top of the hill at the same time as an identical toboggan, loaded with 4 people. a. Which toboggan will reach the bottom of the hill first? b. If you took a toboggan down a 2% grade slope, for a 1000 foot run, and then you took the toboggan down a steeper route of 15% grade down the hill, how would that affect...

PLEASE SHOW WORK!!!
A physics student uses a sled to slide down an icy hill. The mass of the student plus the sled is 60 kg; the hill is 36 meters long, and has an altitude of 10 m. On the level surface just before the slope, the sled is moving at 6 m/s. In fact, when the sled reaches the bottom of the hill, it is only moving at 12 m/s. The physics student therefore concludes that there was...

You are about to ride a steel sled down a surface of ice with an incline of 50 degrees to the horizontal and a distance of 200 m to the bottom of the hill. Draw a free-body diagram for the instant it starts moving. What is the resulting force and acceleration the instant after it starts moving? What is the velocity at the bottom of the hill (initial velocity=0) mus of s= 0,03, mus of k= 0.015. The total mass...

A sled starts from rest at the top of a hill and slides down with a constant acceleration. At some later time the sled passes a red flag stuck into the snow at an unknown distance from the top of the hill; 2.00 s after passing the red flag the sled is 15.91 m m past the red flag; and another 2.00 s later, the sled is now 37.63 m m past the red flag. A. I found the acceleration to be...

A sled with mass 30 kg slides 40 m down a hill angled at 20 degrees to the horizontal. The coefficient of friction between the sled and the ground is 0.2. a) How much work does gravity do on the sled? b) How much work does the normal force do on the sled? c) How much work does friction do on the sled? d) What is the net work done on the sled e) if the sled begins at rest...

In Madagascar, where snow is in short supply, children sled down steep dirt hills on wood and cardboard planks. Two boys want to figure out how much faster one sled is compared to the other. The coefficient of kinetic friction between a dirt surface and wood is uk = 0.158; the coefficient of kinetic friction between a dirt surface and cardboard is uk = 0.390. If they both start from rest at the top of the hill, which has a...
