The coefficient of kinetic friction for a 22-kg bobsled on a track is 0.10. What force is required to push it down along a 6.0° incline and achieve a speed of 60 km/h at the end of 75 m?
The coefficient of kinetic friction for a 22 kg bobsled on a track is 0.10. What force is required to push it down a 6o incline and achieve a speed of 60 km/h at the end of 75 m?
Answer to Problem 61P
Solution:
Force required = 39.65N
Explanation of Solution
Given:
m =22kg
θ=6o
d=75m
v=60km/h=16.67m/s
Formula used:
Calculation:
(16.67)2 = 2(a)(75)
