Answer:

Sure! To find the initial velocity of JB on his motorcycle as he ramps a 100m wide canyon, we can use the formula for horizontal distance traveled by a projectile: d = v * T , where D is the horizontal distance traveled, v is the initial horizontal velocity, and T is the time of flight.

In this case, the horizontal distance traveled d is 100m and the time of flight t is 5 seconds. Plugging these values into the formula above, we get:

100m = v * 5s

Solving for V , we find that the initial velocity of JB on his motorcycle is 20 m/s.
