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:        °

Two bulldozers are pushing against a large pile of dirt.  The first bulldozer pushes with a force, F1 =  20.5  kN at an angle of 10.0 degrees East of North.  The second bulldozer pushes with a force, F2 = 15.7 kN at an angle of 20 degrees West of North.  Friction forces between the pile of dirt and the ground produce a force of 10.7 kN, straight South.  Determine the total force, in kiloNewtons, on the pile of dirt.  Note that a  kN = kiloNewton = 103 N

A mountain climber, in the process of crossing between two cliffs by a rope, pauses to rest. She weighs 570 N. As the drawing shows, she is closer to the left cliff than to the right cliff, with the result that the tensions in the left and right sides of the rope are not the same. Find the tensions in the rope to the left and to the right of the mountain climber. 65.0° 80.0° TL = TR = i

A tractor is being used to pull two large logs across a field. A chain connects the logs to each other; the front log is connected to the tractor by a separate chain. The mass of the front log is 180 kg. The mass of the back log is 220 kg. The coefficient of friction between the logs and the field is approximately 0.45. The tension in the chain connecting the tractor to the front log is 1850 N. Determine the acceleration of the logs and the tension in the chain that connects the two logs.

A block having a mass of m = 19.5 kg is suspended via two cables as shown in the figure. The angles shown in the figure are as follows: α = 12° and β = 35°. We will label the tension in Cable 1 as T1 and the tension in Cable 2 as T2 a)Write an expression for the sum of forces in the x direction in terms of T1, T2, m, g, α, and β. Use the specified coordinate system.  b)Write an expression for the sum of forces in the y direction in terms of T1, T2, m, g, α, and β. Use the specified coordinate system.  c)Solve for the numeric value of T1, in newtons.  d)Solve for the numeric value of T2,in newtons

Two forces, F₁ and F2, act at a point. The magnitude of F₁ is 8.50 N, and its direction is an angle 65.0° above the negative direction of x-axis in the second quadrant. The magnitude of F2 is 5.00 N, and its direction is an angle 52.1° below the negative direction of x-axis in the third quadrant. What is the x-component of the resultant force? What is the y-component of the resultant force? What is the magnitude of the resultant force?

A block of mass m1 = 4.0 kg on a frictionless plane inclined at angle θ = 30.0° is connected by a cord over a massless, frictionless pulley to a second block of mass m2 = 3.0 kg as shown below. What are: a)   the magnitude and direction of the acceleration of each block, b)   the tension in the cord?

a 70kg man successfully pushes a 200kg refrigerator up a 20 angle inclinded slope. he applies a force of 3kN, parallel to the surface of the incline, pushing northwest (north meaning up in this context). friction between the refrigerator and the surface of the incline is 300 Newtons. the normal force acting on the refrigerator is 1.842 kN. choose +x axis to point eastward +y axis to point upward. calculate the weight of the refrigerator

A firefighter with a weight of 779 N slides down a vertical pole with an acceleration of 3.11 m/s2, directed downward. What are the magnitudes and directions (choose the positive direction up) of the vertical forces (a) on the firefighter from the pole and (b) on the pole from the firefighter? (a) Number i Units (b) Number i Units

A mountain climber, in the process of crossing between two cliffs by a rope, pauses to rest. She weighs 515 N. As the drawing shows, she is closer to the left cliff than to the right cliff, with the result that the tensions in the left and right sides of the rope are not the same. Find the tensions in the rope to the left and to the right of the mountain climber.
