1.6. Relative Velocities

Question 1

Relative Velocities

Answer 1

• Let Sa be the distance travelled by object A, and Sb for object B

Sa = ut + 0.5at^2 Sb = ut + 0.5at^2

If a collision occurs at point C then Sa + Sb = D

• This gives you the time of when the collision occurred
• Same analysis if motion is vertical
