Question

a scooter travelling at 10m/sspeed up to 20m/s in 4sec.Find the acceleration of scooter​

Answer 1

Answer:

$2.5m {s}^{ - 2}$

Explanation:

Initial velocity (u) = 10 m/s

Final velocity (v) = 20 m/s

Time (t) = 4s

Acceleration (a) = ?

We know,

$v = u + at \\ a = (v - u) \div t \\ a= (20 - 10) \div 4 \\ a = 10 \div 4 \\ a = 2.5m {s}^{ - 2}$
