2. For each of the following motions draw a motion diagram, a position-vs-time graph, and a velocity-vs-time graph. a. A car starts from rest, steadily speeds up to 40 mph in 15s, moves at a constant speed for 30s, b. then comes to a halt in 5s A rock is dropped from a bridge and steadily speeds up as it falls. It is moving at 30 m/s when it hits the ground 3s later. Think carefully about the signs.

a baseball pitcher throws a baseball (145 grams) towards the batter at a speed of 35 m/s. the batter swings her bat (940 grams) with an unknown speed towards the ball. the bat hits the ball, and the ball goes flying back toward the pitcher at a higher speed. if the ball's speed (not velocity) increases by about 20% and the bat's speed decreases by about 50%, what was the initial speed of the bat before it hit the ball?...
Now assume that the pitcher throws a 0.145 kg baseball parallel to the ground with a speed of 32 m/s in the +x direction
Now assume that the pitcher throws a 0.145 kg baseball parallel to the ground with a speed of 32 m/s in the +x direction. The batter then hits the ball so it goes directly back to the pitcher along the same straight line. What is the ball's velocity just after leaving the bat if the bat applies an impulse of -8.4 N*s to the baseball? I just cant figure out how to do this problem. Please help!

For this question, we will analyze a baseball pitch. The Scenario: You are at a Baseball game in Pontianak, Indonesia. The pitcher throws a 98 mph fastball, and it strikes the batter. The pitch did not have any spin on the ball and there was no wind The umpire decides...

1. In Major League Baseball, a typical fastball is pitched at a speed of about 90 mph, or 40 m/s. The batter can perform the remarkable task of completely reversing the direction of this ball and sending it back at about 105 mph, or 47 m/s. Doing this at just the right millisecond to get the ball to go where the batter wants it to go is such an amazing feat that a Yale physicist once jokingly declared that hitting...

Learning Goal: To understand
the relationship between force, impulse, and momentum. The effect
of a net force ΣF⃗ acting on an object is related both to the force
and to the total time the force acts on the object. The physical
quantity impulse J⃗ is a measure of both these effects. For a
constant net force, the impulse is given by J⃗ =F⃗ Δt. The impulse
is a vector pointing in the same direction as the force vector. The
