You and your friend are moving a stalled car with a mass of 150.0 kg. Your friend is pullingit on one end with a 25.0 N force while you are pushing it from the other end with a forceof 35.0 N. Kinetic friction is also acting between the wheels and the surface of the road. Thecar moves from rest and after 5.0 s the speed becomes 1.0 m/s.(a) Draw the free-body diagram of the car.(b) Solve for the coefficient of kinetic friction between the tires of car and the road.

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?
Skyler has been assigned the noble task of baby-sitting Casey, his 2-year old brother. He puts a crash helmet on Casey, places him in a red wagon and takes him on a stroll through the neighborhood. As Skyler starts across the street, he exerts a 56.9 N forward force on the wagon. There is a 23.1 N resistance force and the wagon and Casey have a combined mass of 33.1 kg. Construct a free body diagram depicting the types of forces acting upon the wagon (upload this as part of your work to be graded). Then determine the acceleration (in m/s2) of the wagon.
Two buckets of sand hang from opposite ends of a rope that passes over an ideal pulley. Onebucket is full and weighs 120 N; the other bucket is only partlyfilled and weighs 63 N. (a) Initially, you hold onto the lighterbucket to keep it from moving. What is the tension in the rope?(b) You release the lighter bucket and the heavier one descends.What is the tension in the rope now? (c) Eventually the heavierbucket lands and the two buckets come to rest. What is the tension in the rope now? Show your work and explain
A box has a mass of 2.50 kg is at rest on a horizontal frictionless surface. Four forces act on the box. The four forces are: F₁ = 20.0 N (North), F₂ = 30.0 N (East), F3 = 15.0 N (South), and F4 = 40.0 N (West). What is the resulting acceleration of the box? Select one: a. b. C. d. 4.47 m/² @ 26.6° (North of West) 31.3 m/2 @ 26.6° (West of North) 31.3 m/2 @ 26.6° (North of West) 4.47 m/2 @ 26.6° (West of North)

An SUV containing 5 passengers has a mass of 3500 kg. It has a driving force of 2500 N directed west on a perfectly horizontal road. The surface of the road exerts a resistive force of 500 N due east. At the same time, a strong wind is blowing a force of 500 N due east in the opposite direction of the car's drive force. Does the car have any acceleration? If yes, then what is the magnitude and direction of the car's acceleration?
A 60 kg block slides along the top of a 100 kg block. The lighter block has an acceleration of 3.8 m/s2 when a horizontal force F= 390 N is applied. Assuming there is no friction between the bottom 100 kg block and the horizontal frictionless surface but there is friction between the blocks. Find the acceleration of the 100 kg block during the time the 60 kg block remains in contact.
Two forces are acting on a 0.150 kg hockey puck as it slides along the ice. The first force has a magnitude of 0.320 N and points 35.0° north of east. The second force has a magnitude of 0.520 N and points 65.0° north of east. If these are the only two forces acting on the puck, what will be the magnitude and direction of the puck's acceleration? Enter the direction as an angle measured in degrees counterclockwise from due east. magnitude of acceleration: m/s2 direction of acceleration: °
A 30.7 kg girl and a 59.8 kg boy are on the surface of a frozen lake, 10.5 m apart. Using a rope, the girl exerts a horizontal 4.20 N force on the boy, pulling him toward her. Calculate the magnitude of the girl's acceleration.
A girl is sledding down a slope that is inclined at 30.0° with respect to the horizontal. The wind is aiding the motion by providing a steady force of 110. N that is parallel to the motion of the sled. The combined mass of the girl and the sled is 73.0 kg, and the coefficient of kinetic friction between the snow and the runners of the sled is 0.190. How much time is required for the sled to travel down a 197-m slope, starting from rest? MO Units
