Figure P4.35F₁= 100 N60°30°XF₂ = 140 N 4.35 Two adults and a child want to push a wheeled cart in the di-rection marked x in Fig. P4.35 (next page). The two adults push withhorizontal forces F₁ and F2 as shown. (a) Find the magnitude and direc-tion of the smallest force that the child should exert. Ignore the effectsof friction. (b) If the child exerts the minimum force found in part (a),the cart accelerates at 2.0 m/s² in the +x-direction. What is the weightof the cart?

Two forces, F and Fact on the 7.00-kg block shown in the drawing. The magnitudes of the forces are F₁-49.7 N and F₂=33.2 N. Take the positive direction to be to the right. Find the horizontal acceleration of the block, including sign. 70.0° 7.00 kg
(optional) A skydiver is weighted 72.7 kg, together with his parachute. The acceleration of gravity is 9.80 m/sec². The air resistance force f to the parachute is proportional to the square of velocity, f = bv², with b = 30.0 Nt sec²/m². Find the expression for his falling speed and the numerical value for his landing speed. When he opens the parachute at t = 0, his falling speed is 10 m/s.

Two blocks with masses m1= 50 kg , m2= 100 kg are connected with a rope. Blocks are pulled with a 20.0 N force making a=30.0 degree angle withhorizontal on a frictionless surface. first question: Show all the forces on the two blocks by drawing a seperate diagram for each block. second question: apply the newton rules and find the tension (T=?) in the rope in between the two blocks.
A 63.0-kg box is pulled by a rope making an angle of θ = 22.0° with the horizontal. The tension in the rope is 34.5 N. (Assume the surface the box slides across is frictionless.)If the box starts from rest, determine the time required to move the box a horizontal distance of 2.67 m.
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.
