A ball is shot from the ground into the air. At a height of 9.80 m,...
A ball is shot from the ground into the air. At a height of 9.80 m, its velocity is v = (8.50i + 4.00j) m/s, with i horizontal and j upward. To what maximum height does the ball rise? What total horizontal distance does the ball travel? What is the magnitude of the ball's velocity just before it hits the ground? What is the angle (below the horizontal) of the ball's velocity just before it hits the ground?

A ball is shot from the ground into the air. At a height of 9.40 m, the velocity is observed to be v = (7.80 m/s) i + (6.40 m/s) j. What is the maximum height that the ball will rise? What will be the total horizontal distance traveled by the ball? What is the x-component of the final velocity of the ball? What is the y-component of the final velocity of the ball when it lands back on the...

a ball is shot straight up into the air and its height above
the ground (in feet) after t seconds is modeled by the functions
s(t)=-16t+127t+8. determines the instantaneous velocity of the ball
two seconds before it hit the ground
9(x) = -1x – 2+4.

A tennis ball is shot straight up from the ground. After traveling 4.00 m, the ball passes a 4.00 m high window and then continues straight up until it loses all its upward velocity and falls to the ground. During the last second of its flight before it hits the ground, the ball drops 20.0 m. a) What is the maximum height above the ground reached by the ball? b) What is the total time for the ball’s flight? c)...
