Two 1 kg blocks are about to slide down frictionless inclined planes as shown below. Each block is 1 m high. Which statement is true
A Block A will have a greater final speed because it has more time to accelerate as it slides down the ramp.
B. Block B will have a greater final speed because the sleeper slope allows it to fall faster
C. Block B will have a greater final speed because friction will have less time to slow it down
D. two blocks will have the same final speed because they have the same potential energy at the beginning of the experiment and will have the san Kinetic energy at the end
