Question

A car starting from rest acquires a velocity 280 cm per second in 0.025min. find the

acceleration​

Answer 1

initial velocity, u = 0m/s

final velcoty, v = 280 cm/s

v = 2.8 m/s

Time, t = 0.025 min

t = 0.025 × 60 sec

t = 1.5 sec

acceleration, a = ( v – u ) / t

a = ( 2.8 – 0 ) / 1.5

a = 2.8 / 1.5

a = 1.866 m/s²

Answer 2

u = 0m/s

v = 280 cm/s =  2.8 m/s

t = 0.025 min = 0.025 × 60 sec = 1.5 sec

a = ( v – u ) / t

a = ( 2.8 – 0 ) / 1.5

a = 2.8 / 1.5

a = 1.866 m/s²
