4. If a rolling cart moves with uniform motion at a rate of 2m/s in the forward direction,what will its displacement be after 5 s? A. 0.4 m B. 2.0 m C. 10 m D. 100 m

Here's how to solve this problem:<br /><br />* **Uniform motion** means the cart is moving at a constant speed.<br />* **Displacement** is the change in position.<br />* The formula for displacement with constant velocity is: displacement = velocity × time<br /><br />Given:<br /><br />* Velocity = 2 m/s<br />* Time = 5 s<br /><br />Calculation:<br /><br />Displacement = (2 m/s) × (5 s) = 10 m<br /><br />Therefore, the answer is C. 10 m<br />
