These pictures show a cart that is moving at constant velocity.
(a) (b) (c) (d)
The cart that is moving at constant velocity
Answer to Problem 1PLA
Option (b)
Explanation of Solution
Constant velocity specifies that the car covers equal amount of displacement in a given time duration. The carts pictured in the question are all moving in a straight line to the left. From the picture, it is evident that the cart (b) gets displaced equally for every 1.00 s.
Conclusion:
From the picture, it is evident that the cart (b) gets displaced equally for every 1.00 s. Therefore, option (b) is correct.
The displacement of cart in (a) is increasing with time, hence the cart a is not moving with constant velocity.
The displacement of cart in (c) is decreasing with time, hence the cart a is not moving with constant velocity.
The displacement of cart in (d) is not uniform, hence the cart a is not moving with constant velocity.
