A tennis player hits a ball at ground level, giving it an initialvelocity of 22.0 at 51.0 above the horizontal.

What are the horizontal and vertical components of the ball'sinitial velocity? in m/s

How high above the ground does the ball go? in m


How long does it take the ball to reach its maximum height? ins
What is the ball's velocity at its highest point? in m/s
What is the ball's acceleration at its highest point? inm/s^2

When this ball lands on the court, how far is it from the placewhere it was hit? in m

On level ground, a cannon fired a cannon ball to a wall with anan initial velocity of 50.0m/s at 60° above the ground and feels no appreciable air resistance. (a) Find the horizontal and vertical component of the cannon ball's initial velocity. (b) calculate the time it takes for the ball to reach its highest point. (c) find  ots maximum height above the ground. (d) computethe horizontal maximum range. (e) without doing any calculations, find the horizontal and vertical components of its velocity and acceleration at the highest point.

A ball is kicked from a location < 9, 0, -6 > (on the ground)with initial velocity < -10, 17, -3 > m/s. The ball's speedis low enough that air resistance is negligible.

velocity of the ball = <-10, 14,06, -3>

What is the average velocity of the ball over this timeinterval?

Use the average velocity to find the location of the ball 0.3seconds after being kicked:



Now consider a different time interval: the interval between theinitial kick and the moment when the ball reaches its highestpoint. We want to find how long it takes for the ball to reach thispoint, and how high the ball goes.

What is the y-component of the ball's velocity at the instant whenthe ball reaches its highest point (the end of this timeinterval)?

Fill in the missing numbers in the equation below (update form ofthe Momentum Principle):
mvyf = mvyi + Fnet,y?t
m( ) = m( )+ -mg?t

How long does it take for the ball to reach its highestpoint?
?t = ( ) s.
Knowing this time, first find the y-component of the averagevelocity during this time interval, then use it to find the maximumheight attained by the ball:
ymax = ( ) m.
