A rock moving in the +x-direction with speed 16.0 m/s has a net force applied to it at time t = 0, and this produces a constant acceleration in the -x-direction that has magnitude 4.00 m/s2. For what three times t after the force is applied is the rock a distance of 24.0 m from its position at t = 0? For each of these three values of t, what is the velocity (magnitude and direction) of the rock?
To understand kinetic and static friction.
A block of mass m lies on a horizontal table. The coefficient of static friction between the block and the table is μs. The coefficient of kinetic friction is μk, with μk<μs.
Suppose you push horizontally with precisely enough force to make the block start to move, and you continue to apply the same amount of force even after it starts moving. Find the acceleration aaa of the block after it begins to move.
Express your answer in terms of some or all of the variables μs, μk, and m, as well as the free-fall acceleration g.
The gravitational force exerted on a baseball is 2.11 N down. A pitcher throws the ball horizontally with velocity 15.5 m/s by uniformly accelerating it along a straight horizontal line for a time interval of 158 ms. The ball starts from rest.
Through what distance does it move before its release?
What are the magnitude and direction of the force the pitcher exerts on the ball? (Enter your magnitude to at least one decimal place.)

According to Aristotle, a body that is stationary will continue to be stationary unless a force is applied to it. According to Aristotle, a falling body accelerates because its weight increases as it approaches Earth’s surface. According to Galileo, a body in motion along a frictionless surface does not need an external force to maintain its motion. According to Galileo, objects fall at the same rate even if one object is more massive than the other object. 1 and 2 3 and 4 1,3, and 4 1,2,3 and 4 Which of the following is a correct explanation to one of the consequences of Special Relativity?
