**please answer the last two parts only.** (f1s & acceleration of block 1) Block 1 (20 kg) is pulled by a rope from left to right up a ramp which is inclined 20 degrees from the horizontal. The rope pulls on block 1 with a force of 340 N parallel to the surface of the inclined plane. The coefficient of kinetic friction between the block and the surface equals 0.4.IN THE SPACE PROVIDED BELOW , draw the free body diagram for block 1 using the two-subscript notation from class. Assume that the x-axis is parallel to the incline and positive in the direction up the incline. After completing the free body diagram, enter below each force and its x & y-components.

. In Figure 1, we have added an inclined plane to our machine. Whenthe masses are let go, they begin to move. There is friction between theinclined plane and m1, the coefficient of which is µk.(a) Draw FBDs for each mass. Take the y-axis to be perpendicular to theplane, and the x-axis parallel to it.(b) Sum the forces in the x- and y-directions.(c) Solve the equations from part (b) for the acceleration.(d) Take your result for the acceleration from part (c) and substituteα = 90◦(we will assume that neither mass contacts the inclined planehere). What equation for the acceleration a do you obtain? How is thisrelated to the standard Atwood Machine we discussed in class?
The contestant now pulls the block of ice with a rope over his shoulder at the same angle above the horizontal as shown below. Calculate the minimum force Fhe must exert to get the block moving. (b) What is its acceleration once it starts to move, if that force is maintained?
In the figure below, there is no friction on the two inclined planes but there is friction between the mass ?2 and the horizontal surface with coefficient of kinetic friction ??. We will assume that the motion of the masses is going to the right.a.) Using 1st and 2nd law of motion, show/prove that the acceleration in terms of
Assume the ramp in the figure below is frictionless. If the blocks are released from rest, does the 10 kg block slide up the ramp or down the ramp? What is the magnitude of its acceleration? (Remember that you do not need to use the same coordinate system for both free-body diagrams.)
Three forces of magnitudes F1=4.0N, F2=6.0N, and F3=8.0N are applied to a block of mass m=2.0kg, initially at rest, at angles shown on the diagram. (Figure 1)In this problem, you will determine the resultant (net) force by combining the three individual force vectors. All angles should be measured counterclockwise from the positive x axis (i.e., all angles are positive). A.) What is the magnitude of the block's acceleration vector, a⃗ ? B.) What is the direction of a⃗ ? In other words, what angle does this vector make with respect to the positive x axis? C.) How far (in meters) will the block move in 5.0 s? Recall that it starts from rest.
The diagram shows overhead views of four situations in which forces act on a block that slides on a frictionless ice surface. In which situations would it be possible for the block to move along the floor with a constant velocity? (Assume the magnitudes of the forces can be adjusted slightly). I do not understand this at all. I know gravitational force is downwards, and frictional force is opposing the pushing force, but how do I solve this?
