Question

A car accelerates from 5 ms to 13 ms in 4.0 s. What is acceleration in ms2?​

Answer 1

Explanation:

Given maximum Velocity is 30 m/s

Distance travelled during acceleration is given by

30

2

−0=2×5×S

1

Hence , S

1

=90m

Distance travelled during retardation

0−30

2

=2×−3×S

2

Hence , S

2

=150m

∴ Total distance travelled is 90+150=240m

Answer 2

Answer:

2 m/s2

Explanation:

Acceleration = Change in velocity / time

= 13 - 5 / 4

= 2 m/s2
