Homework Help: physics

A 4 kg block and a 45 kg block are placed side-by-side at the top of a frictionless ramp. Each is given a very light tap to begin their race to the bottom of the hill. In the absence of air resistance

a. the 4 kg block wins the race.

b. the 45 kg block wins the race.

c. the two blocks end in a tie.

d. there’s not enough information to determine which block wins the race.

I think it is b or c but I am second guessing myself

With zero friction, or equal friction coefficients for both blocks, and zero air resistance, they end in a tie.
