8.A body moving with acceleration covers a displacement of 5m in 2s. Find thevelocity after 2s if its initial velocity is 1m/s.a) 2 m/sb) 3m/sb) 3m/sc) 4m/sd) 5m/sA uniformly accelerated car is found to norcore the solecitine 125 m/s and 135

Answer»

Using,s = ut + 1/2 at^25 = 1*2 + 1/2 * a * (2)^25 = 2 + 2a2a = 3a = 3/2 m/s^2

Now,Using v = u + atv = final velocity

v = 1 + 3/2 * 2v = 1 + 3 = 4 m/s

(c) is correct option
