Kinematics question on a motorcycle

Click For Summary
A motorcycle stunt rider attempts to leap across a 30m wide river using a 100m ramp that is 20m high at its peak. The rider accelerates from rest and takes off at a speed of 20 m/s, moving parallel to the ramp. Key calculations involve determining the maximum height above the river, the time of flight, and the landing distance from the river bank, with discussions focusing on resolving the initial velocity into vertical and horizontal components. The maximum height reached is calculated to be 20.8 meters, while the time to land on the opposite bank requires careful consideration of vertical and horizontal motion. The complexity of the problem highlights the importance of understanding kinematic equations and vector components in projectile motion.

ow...i was calculating using vectors...
a2+b2= c2...

hage- iv done a leve maths and physics ...so i aint a total beginer...

sqaure root of (19.6^2 + 16^2) = 25m/s is the total velocity at -39.2 degrees
with respect to the horizontal

Well when I say use Pythagorus and you don't, what else am I to assume!? :smile:

That answer looks reasonable to me.
