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.

A force in the +x-direction with magnitude F(x) = 18.0 N – (0.530 N/m)x is applied to a 5.00- kg box that is sitting on the horizontal, frictionless surface of a frozen lake. F(x) is the only horizontal force on the box. If the box is initially at rest at x = 0, what is its speed after it has traveled 11.0 m? ( draw free-body diagram)
Whether or not an object (such as a plate, glass, or bone) breaks upon impact depends on the average force exerted on that object by the surface. When a 2.5 kg glass figure hits the floor, it will break if it experiences an average force of 538 N. When it hits a tile floor, the glass comes to a stop in 0.020 s. From what minimum height (in m) must the glass fall to experience sufficient force to break? m How would your answer change if the figure were falling to a padded or carpeted surface? Explain. The duration of the collision would be shorter, so the average force for a given change in momentum would be more.The duration of the collision would be longer, so the average force for a given change in momentum would be less. The duration of the collision would be longer, so the average force for a given change in momentum would be more.The duration of the collision would be shorter, so the average force for a given change in momentum would be less.
As a protest against the umpire's calls, a baseball pitcher throws a ball straight up into the air at a speed of 21.5 m/s. In the process, he moves his hand through a distance of 1.45 m. If the ball has a mass of 0.150 kg, find the force he exerts on the ball to give it this upward speed. MY NOTES ASK YOUR TEACHER
Block A rests on a horizontal tabletop. A light horizontal rope is attached to it and passes over a pulley, and block B is suspended from the free end of the rope. The light rope that connects the two blocks does not slip over the surface of thè pulley (radius 0.080 m) because the pulley rotates on a frictionless axle. The horizontal surface on which block A (mass 3.70 kg) moves is frictionless. The system is released from rest, and block B (mass 6.00 kg) moves Part A What is the tension force that the rope exerts on block B? downward 1.80 m in 2.00 s.

Dwayne ‘The Rock’ Johnson needs to escape from the fourth floor of a burning building (in a movie). He ties a rope around his waist and ties the other end to a 63 kg desk. Then he climbs out of a window and begins to lower himself down. The rope becomes taught when he lets go of the window sill. Then the desk begins to slide on the floor and he starts to accelerate downwards (starting from rest). Dwayne has a mass of 118 kg. The smooth window sill acts as a frictionless pulley. The desk is 10 m from the window. The kinetic friction of the desk sliding on the flooris 370 N. How fast is he travelling when th desk reaches the window?(Hint: Unbeknownst to the audience, The Rock aced Physics 1200 and knows that the tension in the rope is not 370 N)
A 1090 kg boat is traveling at 92 km/h when its engine is shut off. The magnitude of the frictional force ?→?f→k between boat and water is proportional to the speed v of the boat: fk = 85v, where v is in meters per second and fk is in newtons. Find the time required for the boat to slow to 46 km/h.
