The coefficient of dynamic friction between the grass and a 200 kg football blocking sled is 0.20. If a 100 kg football player only pushes horizontally against the sled, how large must the horizontal force be to keep the sled moving at constant velocity?

Question
The coefficient of dynamic friction between the grass and a 200 kg football blocking sled is 0.20. If a 100 kg football player only pushes horizontally against the sled, how large must the horizontal force be to keep the sled moving at constant velocity?
Possible formulas:
Fd=udR
F=ma
Expert Solution
Step 1
Given dynamic friction between the grass and a 200 kg football sled is 0.2.
Mass m= 100kg
We have to find how large the sled moving at constant velocity
