The gravitational force exerted on a baseball is 2.00 N down. A pitcher throws the ball horizontally with velocity 12.0 m/s by uniformly accelerating it along a straight horizontal line for a time interval of 200 ms. The ball starts from rest. a) Through what distance does it move before its release? b) What are the magnitude and direction of the force that exerts on the ball? (Enter your magnitude to at least one decimal place.)

A crate of mass m = 2.00 kg is released from rest at the top of an inclined plane as seen in the figure. The crate starts out at height = 0.100 m above the top of the table, the table height is H = 2.00 m, and 0 = 41.0⁰. H ↑ h i (a) What is the acceleration (in m/s2) of the crate while it slides down the incline? m/s² m (b) What is the speed (in m/s) of the crate when it leaves the incline? m/s (c) At what horizontal distance (in m) from the end of the table will the crate hit the ground? m O No (d) How long (in s) from when the crate is released does it hit the ground? S (e) Does the crate's mass affect any of your above answers? Yes

Two fan carts are on parallel inclined tracks are facing opposite directions. At t=0, the carts are 2.88 m apart with the fans on and they are both given a sharp push toward each other against the direction the fans are pushing them. Cart A begins (after the push) with a speed of 1.35 m/s to the right and has an acceleration of 0.44 m/s? to the left. Cart B begins (after the push) with a speed of 1.05 m/s to the left and has an acceleration to the right of 0.52 m/s?. (Hint: Keep your positive and negative directions consistent for both carts.) A a) At what two times do the two cars pass each other? b) What are the two positions at which the cars pass each other? c) What is the velocity of each car when they pass each other? d) Graph the motion of each on the position vs. time graphs and velocity vs. time graphs on the next page. time (s) time (s) (w) uojiisod velocity (m/ş)

A rocket is launched at an angle of 60.0° above the horizontal with an initial speed of 95 m/s. It moves for 3.00 s along its initial line of motion with an acceleration of 32.0 m/s2. At this time its engines fail and the rocket proceeds to move as a free body. a. Find the maximum altitude reached by the rocket. _______m b. Find its total time of flight. _______ s c. Find its horizontal range _______ m
