Does changing the mass of the object affect the acceleration? I was to conduct an experiment where the motion of an object sliding on an inclined air track under the influence of gravity is observed. In order to demonstrate the effects of force while minimizing friction, the air track has lines of holes drilled along the top faces.

A crate is moving as shown is slowed down by a pushing force P. The force P has a horizontal component of 200 newtons to the left and a vertical component 300 newtons down. The mass of the crate is 90 kgs and the coefficient of kinetic friction is 0.2 and static friction is 0.4. V P What is the magnitude of the acceleration of the crate? Answer in m/s². Use g = 10 m/s². Don't guess! Use the free body diagram method.

Consider an object on an incline where friction is present. The angle between the incline and the horizontal is θ and the coefficient of kinetic friction is μk. a.)  Find an algebraic expression for the acceleration of this object. Treat down the incline as the positive direction. b.) Calculate the acceleration, in meters per second squared, of this object if θ = 31° and μk = 0.34. Treat down the incline as the positive direction.

A semi is traveling down the highway at a velocity of v = 39.5 m/s. The driver observes a wreck ahead, locks his brakes, and begins to slide. The truck has mass m and a coefficient of kinetic friction between the tires and the road of μk = 0.25. Write an expression for the sum of the forces in the x-direction for the truck while braking. Using the results from that input an expression for the trucks acceleration, ax, while braking. What is the magnitude of the acceleration in m/s^2, and how far does the truck travel, d in meters, before stopping?

A 4 kg block is sliding down a vertical wall while being pushed by an external force as shown in the figure. What is the magnitude of the acceleration of the block (in m/s2) if the coefficient of kinetic friction between the wall and the block is uj, = 0.20 and the magnitude of the external force is 20 N? 4 kg 30 X 8.8

You are quite excited with the lesson in friction that you learned in Physics 1A that you decide to measure the coefficient of kinetic friction of surfaces. You try your idea on a glass surface and a glass cup (mass = 0.15 kg). You set the glass cup moving with an initial speed of 2.8 m/s. After travelling a length of 1 m, it stopped. What then is the coefficient of kinetic friction of the glass-glass surfaces?

The following figure shows the acceleration of objects of different mass that experience the same force. Suppose a0 = 6.0m/s^2. What is the magnitude of the force? Express the answer in two significant figures.
