- A 100-kg ice hockey player collides head-on with a 70-kg player. If the first player exerts a force of 500 N on the second player, how much force is exerted by the second player on the first? 100 kg 70 kg - 500 N - 1000 N The coefficient of static friction between a sled and the snow is 0.3, with a coefficient of kinetic friction of 0.2. A 500 N female sits on the 100 N sled. How much force directed parallel to the horizontal surface is required to start the sled in motion? 90 N 180 N 270 N 360 NDetermine the average force that the water exerted on her while stopping her.A 1700 kg car is driving down a highway at a constant velocity when a deer jumps out onto the road 59.6 m ahead. The coefficient of friction between the car tires and the road is 0.21. Calculate the initial velocity of the car if it is able to stop just before hitting the deer. (You do not need to account for reaction time of the driver. Assuming the car is breaking the entire 59.6 m distance and that friction is the only force stopping the car.) v0 = m/s
