From the top of a 70 m building, you throw a ball straight up at 6 m/s. The ball misses the building on the way down. What is the maximum height of the ball? What is the velocity of the ball after 2 s? What is the final velocity of the ball (just before it hits the ground) Now, the ball is thrown straight down at 6 m/s. What is the velocity of the ball after 2 s? Using the initial...

From the top of a building, you throw a ball upward
with initial velocity of 4.00 m/s at an angle of 50 degrees with
respect to the horizontal. a) what are the velocity components of
the ball at point A, B, C, and D? b) how far from the building is
point D?

You are in the middle of a football field and you throw a ball straight up in the air and you catch the ball at the same height at which you let it go. While ignoring air resistance (drag), sketch the Velocity vs. Time and Acceleration vs. Time curves for the ball once it was released from your hand until you catch it. Be sure to title and label everything on the graphs. Label the points on the curve when...

A model rocket is shot straight up and explodes at the top of
its trajectory into three pieces as viewed from above and shown in
the figure below. The masses of the three pieces are
mA = 110.0 g,
mB = 20.0 g,
and
mC = 30.0 g.
Immediately after the explosion, piece A is traveling at 1.40
m/s, and piece B is traveling at 6.90 m/s in a direction 30° below
the negative x axis as shown. What is...

Observer A stands at the top of the cliff and throws a ball straight upwards with a speed of 30 m/s. Observer B is flying in a helicopter that is going straight upward with a speed of 30 m/s. At the moment that observer B passes observer A, B releases a ball. B simply lets go of the ball and does not throw it. (Assume that air resistance has a negligible effect on the balls.) Be sure to include direction...

1. When you drop a ball it accelerates downward at 9.8 m/s. If you instead throw it downward, then its acceleration immediately after leaving your hand, assuming no air resistance, is A. 9.8 m/s2 B. More than 9.8 m/s C. Less than 9.8 m/s D. Cannot say, unless the speed of the throw is given. 2. A heavy rock and a light rock in free fall (zero air resistance) have...
