If the 50-kg crate starts from rest and achieves a velocity of v = 4 m/s when it travels a distance of 5 m to the right, determine the magnitude of force P acting on the crate. The coefficient of kinetic friction between the crate and the ground is μ_k = 0.3.

 Starting from rest, a bicyclist travels around a horizontal circular path, p= 10 m, at a speed of v= (0.09t² + 0.1t) m/s, where t is in seconds. Determine the magnitudes of her velocity and acceleration when she has traveled s = 3 m.
