Answer:
<u>Acceleration is 2 m/s² </u>
<u>Distance</u><u> </u><u>is</u><u> </u><u>1</u><u>0</u><u>0</u><u> </u><u>m</u>
Explanation:
From definition of acceleration, Acceleration is the rate of change in velocity.
• Simplifying the definition, or modifying it;
• Let's formulate symbols:
- a is acceleration
- v is final velocity, v = 20 m/s
- u is initial velocity, u = 0 m/s [ at rest ]
- t is time, t = 10 seconds
Distance = ut + ½at²
Distance = (0 × 10) + (½ × 2 × 10²)
Distance = 0 + 10²
Distance = 100 meters
