PLEASE ANSWER QUICKLY

V- 15 m/s 30° B LA 4 1.5 m 18 m Figure Q2
Transcribed Image Text:V- 15 m/s 30° B LA 4 1.5 m 18 m Figure Q2
The man stands 18 m from the wall and throws a ball at it with the speed of 15 m/s as shown Q2 in Figure Q2. He release the ball at an angle of 0= 30° so that it strikes point B at the height| of h1. The ball reached the maximum height at C. (a) Find the component of velocity in x-direction just before it hit the wall at point B. (b) Calculate the time of flight of the ball from A to B. Determine the height of h, when the ball reach angi hit the wall at point B. of velocity Find the magnitude and direction/of the ball just before it hit the wall at point B. (c) (d) (e) Determine the maximum height of hz and the horizontal distance of xe.
