μ1. The problem statement, all variables and given/known data Hi Im a new user here.. i have problem with my physics homework... can you help me? Like this one.. I'm really really stuck for about 3 hours.. 1. A participant in a winter games event pushes a 50-kg block of ice across a frozen ice lake with a force F directed at 25 degree below the horizontal. if the coefficient of kinetic and static friction are 0.03 and 0.1 respectively, a) calculate the minimum force to get the block moving b) calculate the acceleration of the block if that force is maintained. c) how long dies it take the contestants to reach a top speed of 5.0m/s? 2. Relevant equations F=ma a=Fnet/m 3. The attempt at a solution I have drawed the free body diagram of this problem..
