Newton's Laws of Motion 1. What force is needed to accelerate a sled (mass=55kg) at 1.4m/s^2 on horizontal frictionless ice? 2. How much tension must a rope withstand if it is used to accelerate a 1210-kg car horizontally along a frictionless surface at 1.20m/s^2? 3. Estimate the average force exerted by a shot-putter on a 7.0kg shot if the shot is moved through a distance of 2.8m and is released with a speed 13m/s.
