Question

A 1-lb block and a 100-lb block are placed side by side at the top of a frictionless hill. Each is given a very light tap to begin their race to the bottom of the hill. In the absence of air resistance, what can you conclude about the outcome of the race?a) The 1-lb block wins the race.

b) The 100-lb 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

Answer 1

(c). The two blocks end in a tie

Step-by-step explanation:

the reason being the absence of any resistance offered to both of the blocks.

if the slope of the hill is for instance 60 deg.

then the acceleration in absence of any resistance is a= 9.81sin(60)

since the acceleration is same then both of the blocks will reach at the same instant
