Question

Question 1: Which of the following graphs is traveling at a constant speed?

Answer 1

1. Graph G

2. B and D only

3. Line segment BC is showing acceleration as the cart is increasing its speed.

4.Yes, the object moves (1) at a steady rate (2) slows down (3) stops and then rolls back, speeding up.

Answer 2

1. Graph G shows constant speed.

2. C is constant speed and A is deceleration. So the answer is B and D only.

3. AB distance is same so car is not traveling. CD car is at constant speed. DE car is decelerating. So the answer is Line segment BC is showing acceleration as the cart is increasing its speed.

4. Yes, the object moves (1) at a steady rate (2) slows down (3) stops and then rolls back, speeding up.
