A cart is set rolling across a level table, at the same speed on every trial. If it runs into a patch of sand, the cart exerts on the sand an average horizontal force of 6 N and travels a distance of 6 cm through the sand as it comes to a stop. It instead the cart runs into a patch of gravel on which the can exerts an average horizontal force of 9 N, how far into the gravel will the cart roll before stopping? (a) 9 cm (b) 6 cm (c) 4 cm (d) 3 cm (e) none of those answers
A baseball catcher is performing a stunt for a television commercial. He will catch a baseball (mass 145 g) dropped from a height of 60.0 m above his glove. His glove stops the ball in 0.0100 s. What is the force exerted by his glove on the ball?
A system can have a nonzero velocity while the net external force on it is zero. Describe such a situation.
4) The graph below shows the force exerted on a rocket-propelled cart on a frictionless track as a function of position. The cart has two rocket engines. One points to the right, which we will call the positive direction. The other points to the left, the negative direction. The cart, which has a mass of 2.3 kg, starts at a position of 0 meters with a velocity to the right of 20 m/s.

An 876 N jumper lands on the floor with a velocity of 6.4 m/s. Assuming no force absorption, calculate the force of landing if he stops in: a) 1/100 s, b)1/4 s, c) What is the relationship of these different forces and injury risk of the athlete? Biomechanically (physically) what will you ask the jumper to do to decrease their injury risk?
10 of 31 Listen Study the scenario. A car is moving along a frictionless surface with a speed of 2 m/s to the left. You and your friend each come over and push the car at the same time. You exert a force of 6 N to the left, while your friend exerts a force of 6 N to the right. According to Newton's first law, how will this action affect the car's motion? The car will speed up because your force is in the same direction of the car's motion, making it speed up. The car will stop immediately because two balanced forces will cause an object to stop moving. The car will continue moving to the left but at a slower speed because your friend's force is going to make the car slow down. The car will continue to move 2 m/s to the left because there are balanced forces acting on it.
a bridge across a small stream is made by supporting a 10m long log with a mass of 75kg with ropes tied at the ends of the log to the tree on the banks. the rope on the right makes a 25 degree angle with the ground. the rope on the left makes a 20 degree angle with the ground. a 25kg child us standing 7.5 m from the left bank. write the net force equation for the y direction. write the net force equation for the x direction. write the torque equation (use the left end of the log as the axis of rotation).
You and a friend are on a road trip when your car runs out of gas only 20 meters from a gas station fortunately you're in Montana so the road is perfectly horizontal. You put the car in neutral and apply a horizontal force of 455 N, while your friend applies a horizontal force of 585 N in the same direction. The cars mass is m= 1600kg. The car begins to move, and you push the car to the pump. The car started from rest when you and your friend began pushing. Ignore all friction and air resistance What is the total force applied? what is the work done by your friend over the trip to the gas station? what is the kinetic energy of your car 3 seconds after the start of your trip to the gas station? what was the work done in the first 3 seconds of the trip?
