1. A particle travels along a straight line with a velocity v = (10 – 4t?) m/s, where t is in seconds. When t = 1 s, the particle is located 10 m to the left of the origin. Determine the acceleration when t = 5 s, the displacement from t = 0 stot = 10 s, and the distance the particle travels during this time period. (10 marks) 2. The 80 kg crate shown below begins to move from rest and travels a distance of 10 m up the plane in 5 seconds. If the coefficient of kinetic friction between the crate and the ground is uk = 0.55: a) Find the acceleration of the crate (3 marks) b) Determine the magnitude of force P acting on the crate.
