A 300-N sled is pulled up a 28° slope at a constant speed by a force of 250 N. What is the normal force on the sled .

A large block is being pushed against a smaller block such that the smaller block remains elevated while being pushed. The mass of the smaller block is m = 0.70 kg. It is found through repeated experimentation that the blocks need to m have a minimum acceleration of a = 12 m/s? in order for the smaller block to remain elevated and not slide down. What is the coefficient of static friction 4, between the two blocks? Us =

Part 1.  We will use a three-wheeled cart on a flat and smooth table. A string is attached to the front of the cart. The other end of the string was wrapped around a smooth pulley with a wight hanger attached to the other end. When we mention the smooth surface of the table and smooth pulley, it means that there is no frictional force affecting the motion. If we add different mass on the weight hanger, we are applying a different pulling force on the cart through the string. If you are given the mass of the cart and given the magnitude of the force, you can calculate the acceleration. We will gradually add the mass on the weight hanger, so we are gradually increasing the pulling force. For each force, you can calculate the acceleration.      Force (F)  on the cart, Newton Mass (m) of the Cart, kg acceleration=FmFm   1 0.5 1.2     2 1.0 1.2     3 1.5 1.2     4 2.0 1.2     5 2.5 1.2     6 3.0 1.2     You also need plot a graph with acceleration as y-axis and Force as…

The friction force that a horizontal surface exerts on a 62 kg object is 23 N. If the initial speed of the object is 27 m/s, what distance will it slide before coming to a stop?

There is a worker that slides a heavy box up a ramp into a truck. The box has a mass of 70 kg.  The ramp is 4.7 m long and makes an angle of 27 degrees with the horizontal. The coefficient of friction between the ramp and box is 0.4  1.What's the weight of the box? 2.What's the normal force acting on box? 3.What's the force of friction acting on box?

A 1500 kg car traveling 30 m/s comes to a stop. The coefficient of friction between the tires and the road is 0.80. What is the acceleration of the car? What is the stopping distance?

What net force is required to make a 15 kg box move at a constant speed of 2.0 m/s.

A 10 kg box experiences a force of 15 Newtons in the positive x-direction and 8 Newtons in the negative y-direction. What is the magnitude of the net force acting on the box? Answer in Newtons.

ou are pushing your friend in his wheelchair. You are both taking his dog, Wrathbone, to the vet. Wrathbone is 5 kg and is sitting in your friend’s lap. You decide to increase the wheelchair’s acceleration to 7 ms2 in order to get up a steep ramp. If your friend has a mass of 46 kg and his wheelchair has a mass of 16 kg. What is the force you are applying?

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?
