3) a) If the coefficient of kinetic friction between the 50-kg crate and the ground is 0.3, determine the distance the crate travels and its velocity when t= 3 sec. the crate starts from rest and p=200 N. b) If the crate starts from the rest and achieves a velocity of v=4 m/sec when it travels 5 m to the right, determine the P. Coefficient of kinetic friction between the crate and the ground is 0.3. 30° P
