A student pushes on a lawn mower from rest parallel to the handle of the mower. The student pushes with a force of magnitude 42 N. The handle makes an angle of 35° to the horizontal. The mower accelerates across a level driveway with negligible friction on the mower toward the lawn, 5.0 m away. The mass of the lawn mower is 18 kg. u M O (a) Draw the FBD of the mower. (b) Calculate the acceleration of the mower. (c) Calculate the normal force acting on the mower. (d) Calculate the velocity of the mower when it reaches the lawn.

How can i solve this exercise?
Please give me a comprehensive solution & include a free body diagram!
Use the figure to answer the question Two blocks are positioned on surfaces, each inclined at the same angle of 57.5 degrees with respect to the horizontal. The blocks are connected by a rope which rests on a frictionless pulley at the top of the inclines as shown, so the blocks can slide together. The mass of the black block is 5.50 kg, and this time there is NO friction. What is must be the mass of the white block if both blocks are to slide to the LEFT at an acceleration of 1.5 m/s^2? a. 7.94 kg b. 4.00 kg c. 11.91 kg d. 5.29 kg
I need help with this question. I also need help with drawing the free body diagram

As seen in the figure, three masses are connected to each other with the system set up on a table. Table friction and kinetic coefficient of friction is 0.35. (g = 10m / s2). a) Draw the free body diagram for each mass.
A crate sits on a rough surface. Using a rope, a man applies a force to the crate as shown in the figure. The force is not enough to move the crate, however, and it remains stationary. If necessary, use Fs for the force of static friction, and Fk as the force of kinetic friction. Draw the Free Body Diagram for the crate.
What is the correct free body diagram for the system and what is the rank of the forces from largest to smallest?
Hello please help me create a free body diagram of this figure and also the force equation
