A ditch 2.5 m wide crosses a trail bike path. An upward incline of 15o has been built up on the approach so that the top of the incline is level with the top of the ditch.(Add 1.4 m to the range for the back of the bike to clear the ditch safely.)

HOW DID YOU CALCULATE THIS ANSWER?
 
Range equation: R = (v^2/g)*sin(2*theta)

so v = (R*g/sin(2*theta))^0.5

v = ((2.5+1.4)*9.8/sin(30 degrees))^0.5

v = 8.74 m/s

hope that helps!
