Block 1 (4.5 kg) is resting on the surface of a table. On a sheet of paper, draw the free body diagram for block 1 using the two-subscript notation from class. After completing the free body diagram, enter below each force and its x & y-components. (use g = 10 m/s2) Remember that the x-component is the "i" component and the y-component is the "j" component. %3D

When traveling on an airplane you get meals on a serving tray that has large coefficients of static and kinetic friction between the tray and dishes on it. Assume the airplane is moving from left to right. Assume also that the tray is parallel to the velocity of the airplane. c. Draw a force diagram for a cup on a serving tray as seen by a stationary observer on Earth if the airplane is on a runway and slowing down; the cup is sliding. Next to the force diagram draw an arrow that shows the velocity of the cup relative to the airplane.

Part A A truck with mass m has a brake failure while going down an icy mountain road of constant downward slope angle a (Figure 1). Initially the truck is moving downhill at speed vo. After careening downhill a distance L with negligible friction, the truck driver steers the runaway vehicle onto a runaway truck ramp of constant upward slope angle B. The truck ramp has a soft sand surface for which the coefficient of rolling friction is lr . What is the distance that the truck moves up the ramp before coming to a halt? Solve using energy methods.

A diagram represents a cart moving on a ramp. Assuming a frictional force of 12.2N. what is the magnitude of the net force acting on the cart.

b. A block of mass m is placed at rest on an inclined plane as shown below. The plane is frictionless and makes the angle with the horizontal as shown. If another force of magnitude P is applied to the block at the known angle as shown, draw the free body diagram for the block and determine what the value of P must be if the block is to remain at rest.

Three blocks (as shown in the figure) are released from rest and they start to accelerate with a constant magnitude of 0.44 m/s². Block A has mass M, block B has mass 1.8 M and block C has mass 2.0M. The value of M is not given. What is the coefficient of kinetic friction between the table and block B? The mass and friction in the pulleys can be ignored. A Question Help: Read Submit Question B C

When serving a tennis ball, the player hits it when its velocity is zero (at the highest point of a vertical toss). The racket exerts a force of 530 N on the ball for 5.00 ms, giving it a final velocity of 44.0 m/s. Using these data, find the mass of the ball. g Additional Materials I Reading

Part A A block lies on a plane raised an angle e fram the horizantal. Three forces act upon the block: Fw, the force of gravity. Fn. the narmal force; and Fr. the force of friction.

If the system isn't accelerating, then you are better off choosing the coordinate system with the most vectors along the coordinate axes. But now you are gaing to ignore that advice.…

An 8.00 kg crate sits on an inclined plane that is inclined at 33.0 above the horizontal. The coefficient of kinetic friction between the crate and the surface of the plane is 0.300. A constant horizontal force F = 28.0 N is applied to the crate (Figure 1), and the crate moves down the plane. Part A If the crate is initially at rest, find its speed 2.00s after the force is applied? Express your answer with the appropriate units.
