Answer 1

Answer:

$10 \: m {s}^{ - 2}$

Explanation:

◆Car covers 20m in first second

◆car covers 30 m in next second means car covers 50 m in 2 seconds.

now using equation for two situations-

●situation 1-

$s = ut + \frac{1}{2} a {t}^{2} \\ s = u \times 1 + \frac{1}{2} a \times {1}^{2} \\ s = u + \frac{1}{2} a \\ 20 = u + \frac{a}{2} \\ 40 = 2u + a - - (1)$

●Now.. situation 2

$s = ut + \frac{1}{2} a {t}^{2} \\ 50 = u \times 2 + \frac{1}{2} a \times {2}^{2} \\ 50 = 2u + 2a - - (2)$

On solving equation 1 and 2-

we get Acceleration = 10m/s^2
