A small car (mass 380 kg) is pushing a large truck (mass 900 kg) due east on a level road. The car exerts a horizontal force of 1200 N on the truck. What is the magnitude of the force that the truck exerts on the car?

Sammy is doing a strength testing session on the turf in preparation for the upcoming basketball season.  Sammy's mass is 55 kg and she is trying to push a 105 kg sled across the artificial turf outside on Raymond Field.  The coefficient of static friction between the sled and the turf is 0.3.  If Sammy pushes only horizontally against the sled, how much force must she push with to just initiate movement of the sled? (hint: be sure to follow the steps outlined for free body diagrams, including drawing the free body diagram with all forces, force equations in the X and Y direction, and a coordinate system)

A car of mass 800 kg as shown in the figure is subject to three forces F1, F2, and F3. The two forces F1=1000 N and F2=500 N are directed along the +X direction. Third force F3 is not shown in the figure. Ignore the effect of frictional force exerted by the tires on the road.         a) Suppose the car is stationary, then what is the direction and magnitude of the force F3?       b) The car started moving and attained a velocity of  +500 m/s in 10 second due a change in F3. What will be the new direction and magnitude of the the force F3?        c) How far does the car traveled during this 10 second time interval?

A hunter is pulling his sled 45 kg in mass behind him on snow. He exerts a pull of 170 N in magnitude and at 21 degrees above the horizontal to ensure he could move at a constant acceleration through the snow-covered land. The coefficient of friction between the sled and the snow is 0.43. What is the hunter's acceleration (could be positive or negative)?

A 1280 kg car pulls a 350 kg trailer. the car exerts a horizontal force of 3.6 x 103 N against the ground in order to accelerate. What force does the car exert on the trailer? Assume an effective friction coefficient of 0.15 for the trailer.

Tom enlists the help of his friend John to move his car. They apply forces to the car. F1 = 430 N and F2 = 347 N and friction is negligible. Mass of car = 3500 kg O1= -25 degrees and O2 = 12 degrees (assume the car faces the positive x-axis before the forces are applied. A) Find the force (in N) exerted on the car     Magnitude =     Direction (counterclockwise from the +x-Axis) = ______________ degrees B) What is the acceleration (in m/s squared) of the car?     Magnitude =   __________ m/s squared     direction (counterclockwise from the +x-Axis) ______________ degrees

A student takes the elevator up to the fourth floor to see her favorite physics instructor. She stands on the floor of the elevator, which is horizontal. Both the student and the elevator are solid objects, and they both accelerate upward at 5.35 m/s2. This acceleration only occurs briefly at the beginning of the ride up. Her mass is 88.0 kg. What is the normal force exerted by the floor of the elevator on the student during her brief acceleration? (Assume the direction is upward.)

A teenager of mass m1 = 61 kg pushes backward against the ground with his foot as he rides his skateboard. This exerts a horizontal force of magnitude Ffoot = 10.5 N. The skateboard has m2 = 2.7 kg.Variables Ffoot = 10.5 Nm1 = 61 kgm2 = 2.7 kg a)Write an expression for the magnitude of the horizontal component of force that the ground exerts on the teenager's foot, Fground. Fground= b) Write an expression in terms of given quantities for the magnitude of the skateboard's acceleration, a, while the teenager is pushing backwards on the ground.

A force of 109 N is used to accelerate a block of ice with a weight of 614 N along a horizontal surface where it encounters a kinetic friction force of 38 N. What is the horizontal acceleration of the block of ice?

At an instant when a soccer ball is in contact with the foot of the player kicking it, the horizontal or x component of the ball's acceleration is 700 m/s2 and the vertical or y component of its acceleration is 750 m/s2. The ball's mass is 0.32 kg. What is the magnitude of the net force acting on the soccer ball at this instant?
