Two blocks of equal mass, size and shape are released from the same height and slide down frictionless inclined planes to the ground. Block A slides down a plane that makes a 30 degree angle with the horizontal. Block B slides down an inclined plane that makes a 60 degree angle with the horizontal. Which block reaches the ground first?

• Block A

• Block B

• They reach the ground at the same time

• Impossible to tell which block reaches the ground first

Two blocks of equal mass, size and shape are released from the same height and slide down frictionless inclined planes to the ground. Block A slides down a plane that makes a 30 degree angle with the horizontal. Block B slides down an inclined plane that makes a 60 degree angle with the horizontal. Which block has the greater speed when they reach the ground?

• Block A

• Block B

• They reach the ground with the same speed

• Impossible to tell which block has the greater speed when they reach the ground
