(a) Calculate the distance and speeded of the cyclist at the end of the 20 seconds. She then travels at the constant speed at the end of her first trip for the next 20s. (b) Calculate the distance she traveled. Finally, the cyclist decelerates at 4m/s^2 and comes to a full stop at a pedestrian crossing. (c) Calculate the distance during deceleration. (d) Find the total distance traveled by the young cyclist. A projectile is shot from a height of 5m above the ground. The initial velocity is given by v vector_0 - v_ i + v_0, j = (40 i + 30 j) m/s Assuming the ball follows a parabolic path: a) Find the time it takes the ball to hit the ground. b) How far in the horizontal direction has the ball traveled? A 30.0 kg block lying on a horizontal is connected to a 60kg block by a cord that passes over a pulley. The 60 block is hanging. The pulley is frictionless and of negligible mass. Neglect the mass of the string. The coefficient of kinetic friction between the 30.0 kg block and the surface is mu_k = 0.20. a) Find the acceleration of the system. b) Find the tension in the cord. c Find the distance the 60 kg mass descends 3 seconds after release.
