Todd and Angela set up a ramp and released several cars from the top. If Todd and Angela want to determine the average speed of their cars down the ramp, what information do they need? Group of answer choices

The ramps length, height, degree, and the weight of the car.

Explanation:

I think they need the slope of the ram(degree) .

& current gravitational acceleration

& the length of the ram and also l don't think mass of the cars are not needed becoz the acceleration of the cars are given by its,

Gravitational acceleration * sin( slope).

So then use that in v^2=u^2+2as equation.

s for length

a for acceleration

v for end velocity

u for start velocity

not moving. pos accel,
