a) 60 = v cos50 t
-25 = v sin50 - 1/2* 9.8* t^2
Solve the first for t and plug into the other
b) deep doo-doo I would assume.
A physics professor moonlights as a daredevil jumping things on a motorbike. His next stunt will be
to jump the oldman river on his motorcycle. The ramp is being built 100 m above the river and made
an angle of 50.0
o
relative to the horizontal. The landing ramp will be 60.0 m away and 25.0 m below
the takeoff ramp. You can ignore air resistance, the stunt rider plans on wearing his speedo and not
his hip hop clothes.
(a) What should be his minimum speed at the top of the takeoff ramp for him to make the landing
ramp?
(b) If his takeoff speed was only half the answer in part (a), where will he land?
