3. An engine exerts a force of 10000 N on a 1000 kg car travelling over a flat road. The force (overcoming friction) accelerates the car from rest such that it travels a distance of 50 m in 5 s Find e. the net acceleration of the car, f. normal force exerted by the road on the car, and g. the coefficient of kinetic friction between the car and the road? 4. A 10 kg block is initially at rest...
You need to push a box across carpet. The box and its contents have a mass of 75 kg. The coefficients of static friction and kinetic friction between the box and the carpet are 0.60 and 0.40, respectively. A. You push horizontally on the box with a force of 300 N. Draw a free-body diagram for this scenario. What is the magnitude of all the individual forces that act on the box? B. You now push horizontally on the box...
You push a box weighing 6.72 kg along a horizontal floor with a force 16.6 N at an angle 38.3⁰ below the horizontal. The coefficient of friction between the box and the floor is 0.116. (a) What is the frictional force on the block? (b) What is the acceleration of the block?
You are pushing horizontally on a couch with a force of 60N, but it's not moving. A) How much friction is present at that moment? You push hard until is start moving. After it is moving across the floor you are pushing it so it is going at a constant velocity of 0.25 m/s. B) If you pushing with a force of 140 N, how much friction force is there between the floor and the couch resisting the motion at...
I push a 16.5-kg box across a floor, which has a kinetic frictional force of Ff = 27.5 N. If my push of FA = 32 N gives it an acceleration of 0.35 m/s2, what is the coefficient of kinetic friction?
A horizontal force of 150 N is used to push a 40.0-kg packing crate a distance of 6.00 m on a rough horizontal surface. if the create moves at a constant speed, (a) find the work done by the 150-N force and (b) the work done by the frictional force.
Question 6 (motion to force) A 1000 kg car with you in it accelerates from rest to 32 m/s in a time of 4 seconds. You are 50 kg. a. With how much force does the ground push the car forward? b. With how much force does the seat push you forward?

Question 1 5 pts A large heavy box sits on a ramp. You need to push it up the ramp. The box does not move. The total mass of the box (and its contents) is M = 45 kg and the applied force is P= 100 N, and the incline of the ramp is 0 = 25 degrees, what are the magnitudes for the following forces? the normal force acting on the box [Choose] the frictional force acting on the...
If you push with a horizontal 650-N force to a 90-kg crate initially at resting on the floor, what must acceleration be? The static and kinetic energy coefficient of friction are us- 0.4, uk= 0.25 respectively.
