Question

A car accelerates uniformly from 10 m/s to 30 m/s in 10 seconds. What is the distance covered?

• A. 250 m
• B. 200 m
• C. 300 m
• D. 400 m

Answer 1

The Correct Option is B

Step 1: Use the formula for uniformly accelerated motion: \[ s = \frac{(u + v)}{2} \cdot t \] Where: \( u = 10\ \text{m/s},\ v = 30\ \text{m/s},\ t = 10\ \text{s} \) \[ s = \frac{(10 + 30)}{2} \cdot 10 = \frac{40}{2} \cdot 10 = 20 \cdot 10 = 200\ \text{m} \] \[ \boxed{200\ \text{m}} \]
