Question

A toy car in the figure below runs off the edge of a table that is h = 1.375 m high. The car lands d = 0.375 m from the base of the table.How fast was the car going on the table?

Answer 1

Let Vo be the initial speed.

Vo remains the horizontal velocity component while it falls.

Vo *(fall time) = 0.375 m

Compute the time T that it takes to fall H = 1.375 m, and use that in the equation above to solve for Vo.

(1/2)gT^2 = H
T = sqrt(2H/g)
