Answer 2

Explanation:

Given :

• Initial velocity (u) = 0 m/s
• Acceleration (a) = 4 m/s²
• Time (t) = 10 sec

To Find :

• The distance covered by it in 10 seconds.

Solution :

Applying 2nd equation of motion,

S = ut + ¹/2 × at²

=> S = 0 × 10 + ¹/2 × 4 × 10²

=> S = 0 + 2 × 100

=> S = 0 + 200

=> S = 200 m

Hence :

The distance covered by it in 10 seconds is 200 m.
