Question

5-Calculate the initial vertical and horizontal velocity from the launch angle and launch velocity .

6. Calculate the time it will take for the projectile to reach the ground. For a positive launch angle, rst calculate how long until the projectile returns to the launch height 2 × (VERTICALVELOCITY / G) . For the fall time

from the launch height to the ground, use (height x 16 / verticalvelocity×15 )which is an approximation. Add these two

height×16 times together, if applicable, to obtain the total flight time.

7. To find the horizontal distance traveled, simply multiply the horizontal velocity by the flight time.

Explanation / Answer

5) let U is initial speed and is angle of projection.

Ucos is horizontal component of velocity.

Usin is vertical component of velocity.

6) Time of flight T=2Usin/g

7)Horizontal range=U^2 sin2/g
