At one instant, a 17.5-kg sled is moving over a horizontal surface of snow at 3.50 m/s. After...
Homework Answers
SOLUTION:
Mass of the sled, m=17.5 kg
Intial speed of the sled, u=3.50 m/s
Final spedd of the sled, v=0 m/s
Time intervel, t=8.75 s
From Newton's second law,
F=ma
=m(u-v)/t
=(17.5 kg)(3.50 m/s- 0 m/s)/(8.75 s)
= 7 N

Question: At one instant, a 17.5-kg sled is moving over a horizontal surface of snow at 3.50 m/s. After 8.75 s has elapsed, the sled stops. Use a momentum approach to find the average friction force acting on the sled while it was moving. Please check my work. If it is incorrect please provide detail. Sled mass (m) = 17.5kg moving over a horizontal surface initial velocity of (U) = 3.5 m/s Initial momentum of the sledge (P1)=mU (P1)=(17.5kg)(3.50 m/s)...

A 17.5 kg block is dragged over a rough, horizontal surface by a constant force of 70.4 N acting at an angle of 27.5◦ above the horizontal. The block is displaced 46.9 m, and the coefficient of kinetic friction is 0.119. The acceleration of gravity is 9.8 m/s2 . 17.5 kg μ = 0.119 Find the work done by the force of friction. Answer in units of J.

QUESTION 3 A 60-kg (including the passenger) sled is subject to a net force of 20 N pushing in the direction of the sled's motion as it is moving over a horizontal surface for a distance of 11 m after having started from rest. At this point the sled is released as it starts down a 10.0" incline. However, the snow is not very deep, and the sled stops after having moved an additional 35 m. What is the work...
