Question 1: Part a: Two bicycles have the following equations of motion:
X1 = -4.2 m + (2.4 m/s)t
X2 = 7.0 m +(-3.7 m/s )t
What is the distance between the bicycles at t=0? Express your answer to three significant figures and include appropriate units.

Part b: What is the distance between the bicycles at t = 1 s ?

Question 2 part a:what is the velocity of an object that moves from 76 m to 66m in 11 s? Express answer in three significant figures and include appropriate units.

Part b: what is the speed of an object that moves from 76 m to 66 m in 11 s?
