The masses of boxes 1, 2, and 3 are m = 3.5 kg, m2 = 4.5 kg, and m3 = 8.0 kg, respectively. The delivery person places the stack of boxes on an elevator floor, which then accelerates upward with a magnitude of a = 0.90 m/s?. Assume that the positive direction is up. Calculate the contact force Fj-2 that box 1 exerts on box 2 during the acceleration. F-2 = N Calculate the contact force F3-2 that box 3 exerts on box 2 during the acceleration. F3-2 = N

50 X 10 X 18.710 7. An airplane of mass 1.5x104 kg moves horizontally at a speed of 60.0 m/s. The pilot then increases the engine's thrust to 7.50 x104 N. The air resistance is 4.00x104 N. Find the speed of the airplane after it has traveled 5.00x10² m horizontally while maintaining a constant altitude.
An electron is a subatomic particle (m= 9.11 x 10-31 kg) that is subject to electric forces. An electron moving in the +x direction accelerates from an initial velocity of +7.31 x 105 m/s to a final velocity of 1.98 x 106 m/s while traveling a distance of 0.0545 m. The electron's acceleration is due to two electric forces parallel to the x axis: F₁ = 7.52 x 10-¹7 N, and F2, which points in the -x direction. Find the magnitudes of (a) the net force acting on the electron and (b) the electric force F2. F₁ F₁ F₂ F₁ (a) Number i (b) Number i VO X Units Units
A force of {N} pushes a 16-kg shopping cart (parallel to a horizontal surface) for a time of 10 seconds. If the cart was initially at rest, what is the final speed?
A teenager is pushing a cart. There is no friction between the cart and the ground. Mass of the cart is 120 kg. Cart is initially at rest (at time = 0 s). Direction to the right is positive. He pushed the cart for 5 s (from t = 0 s to t = 5 s) with a force of 75 N to the right hand side. Then he stopped pushing for 5 s (from t = 5 s to t = 10 s). Then he pushed the cart for 10 s (from t = 10 s to t = 20 s) with a force of 75 N to the left hand side. Question: Calculate the kinetic energy of the cart at t = 5 s.
Mary applies a force of 78 N to push a box with an acceleration of 0.49 m/s2. When she increases the pushing force to 86 N, the box's acceleration changes to 0.73 m/s2. There is a constant friction force present between the floor and the box. (a) What is the mass of the box in kilograms? kg (b) What is the coefficient of kinetic friction between the floor and the box?

An 85 kg man lowers himself to the ground from a height of 10.0 m by holding onto a rope that runs over a frictionless pulley to a 65 kg sandbag. With what speed does the man hit the ground if he started from rest?
In the figure, a body with a mass of 2 kg moves under the influence of two constant forces F1 = 5N and F2 = 4N in the xy plane. At time t = 0, the object is at point 0 and its speed is V = 2i + j (m / s). What is the acceleration of the particle and its position after 2 seconds in terms of the unit vector?
A 1.90 kg box is moving to the right with speed 9.00 m/s on a horizontal, frictionless surface. At t = 0 a horizontal force is applied to the box. The force is directed to the left and has magnitude F(t)=( 6.00 N/s^2 )t2 If the force continues to be applied, what is the velocity of the box at 3.50 s?
Dana loads luggage into an airplane using a conveyor belt tilted at an angle of 20°. She places a few pieces of luggage on the belt before it starts to move, then she turns the belt on. It takes the belt 0.70 s to reach its top speed of 1.2 m/s. Does the luggage slip? Assume μs = 0.50 between the luggage and the belt.
A fire breaks out on a high rise building and a rescue helicopter is called to the scene. The helicopter is equipped with a rescue basket attached by a strong cable to a winch on the helicopter. The rescue basket is lowered to the roof and some occupants of the top floor escape to the roof and enter the basket. As the helicopter takes off, the cable momentarily makes a 78.2° angle to the horizontal, imparting a slight horizontal acceleration to the 621-kg basket and occupants across the roof top. The coefficient of friction between the basket and the roof top is 0.568 and the tension in the cable is 4980 N. Determine the acceleration of the basket and occupants. (Suggestion: Begin with a free body diagram.)
A bead with mass 1.80 × 10-2 kg is moving along a wire in the positive direction of an x axis. Beginning at time t = 0, when the bead passes through x = 0 with speed 12.0 m/s, a constant force acts on the bead. The figure indicates the bead's position at times t0 = 0.00 s, t1 = 1.00 s, t2 = 2.00 s, and t3 = 3.00 s. The bead momentarily stops at t = 3.00 s. What is the kinetic energy of the bead at t = 10.0 s?
