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:* **Uniform motion** means the cart is moving at a constant speed.* **Displacement** is the change in position.* The formula for displacement with constant velocity is: displacement = velocity × timeGiven:* Velocity = 2 m/s* Time = 5 sCalculation:Displacement = (2 m/s) × (5 s) = 10 mTherefore, the answer is C. 10 m
