Compute all parts of give problem:
Problem: A contestant in a winter games event pushes a 35.0 kg block of ice across a frozen lake. The coefficient of static friction is 0.1 and the coefficient of kinetic friction is 0.03. (Assume θ = 29°.)
Part A: Calculate the minimum force F he must exert to get the block moving?
Part B: What is its acceleration once it starts to move, if that force is maintained?
I need help to find the minimum force F he must exert to get the block moving.
