Physics

A contestant in a winter games event pushes a 46.0 kg block ofice across a frozen lake as shown in the figure below. Thecoefficient of static friction is 0.1 and the coefficient ofkinetic friction is 0.03. (Assume θ = 25°.) (a) Calculate theminimum force F (in N) he must exert to get the block moving. 49.7Correct: Your answer is correct. N (b) What is its acceleration (inm/s2) once it starts to move, if that force is maintained?Incorrect: Your answer is incorrect. Consider Newton's Second Law.m/s2
