Question

A 1-kg standard cart collides with a cart A of unknown inertia. Both carts appear to be rolling with significant wheel friction because their velocities change with time as shown in (Figure 1)

1) What is the standart cart velocity at t = 0, t = 5.0 s, t = 6.0 s , and t = 10 s ?

Express your answers in terms of unit vector i^. To denote unit vectors in your answer, be sure to select the 'unit vector' button. Express your answers using two significant digits separated by commas.

v? 0, v? 5, v? 6, v? 10 = ????

2) What is the cart A velocity at t = 0, t = 5.0 s , t = 6.0 s , and t = 10 s ?

Express your answers in terms of unit vector i^. To denote unit vectors in your answer, be sure to select the 'unit vector' button. Express your answers using two significant digits separated by commas.

?????

3) What is the inertia of cart A?

Express your answer to two significant digits and include the appropriate units.

4) When not colliding, are the carts speeding up or slowing down? Choose from:

a) The cart A is speeding up but the standard cart is slowing down.

b) the cart A is slowing down but the standard cart is speeding up

c) Both carts are slowing down

d) Both carts are speeding up

5) Is the acceleration of each cart the same before and after the collision? Choose from:

a) The acceleration of the cart A changes but the acceleration of the standard cart is the same

b) the acceleration of both carts is the same

c) the acceleration of both carts change

d) The acceleration of the cart A is the same but the acceleration of the standard cart changes.

?????
