Astudent is skateboarding down a ramp that is 7.76 m long and inclined at 26.3° with respect to the horizontal. the initial speed of the skateboarder at the top of the ramp is 3.07 m/s. neglect friction and find the speed at the bottom of the ramp.

Final velocity will be 6.566 m/sec

Explanation:

We have given distance s = 7.76 m

Initial speed u = 3.07 m/sec

Let m be the mass of the scallerer

Force acing down the ramp is the sinθ component of the force due to gravity and this = mg

Acceleration down the ramp =

Speed at the bottom of the ramp can be found out using,

According to third equation of motion

So

v = 6.566 m/sec
