- John throws a baseball from the outfield from shoulder height , at an initial velocity of 29.5 m/s at an initial angle of 45.0 degrees with respect tot he horizontal. The ball is in its trajectory for a total interval of 3.00 s before the third basemen catches it at an equal shoulder-height level. (Assume sir resistance negligible) What is the balls horizontal displacement?A BMX bicycle rider takes off from a ramp at a point 2.4 mm above the ground. The ramp is angled at 40∘∘ from the horizontal, and the rider's speed is 6.3 m/sm/s when he leaves the ramp. At what horizontal distance from the end of the ramp does he land?A ball is launched from ground level at 25 m/s at an angle of 55^o above the horizontal.how far doe it go before it is at the ground level again?

What are the horizontal and vertical components of the walnut’s velocity just before it reaches the ground?A major league baseball player hits a fly ball. The ball leaves the bat with a velocity of 41 m/sat an angle of 72o above the horizontal. How far from home plate does the center fielder need to stand if he is going to catch the ball at the same height from which it was hit?

- To have anv hone of making nar on a hole. a golfer has to hit the next shot over some nearby trees and past a water hazard, whose far side is located-on level ground 100 m away. The ball is hit with an initial speed of 30 m/ at an angle of 45°, allowing it just to clear the trees. Does the ball get past the water hazard? 100 mA basketball is launched with an initial velocity Voat an angle 0 = 40° above the horizontal follows the trajectory shown in the figure. The ball enters the basket 0.6 s after it is launched. The horizontal distance '1' of the ball from it was launched to the pole is 4 m. Calculate the initial velocity v, of the ball.47.
