Question

A car has a uniform acceleration of 3.5m/s2. Calculate the distance travelled by the car after 10 seconds of start?

Answer 1

Answer: 175m

Explanation:

a=3.5ms~²

t=10sec

u=0 ms~¹

By second equation of motion,

S=ut +½at²

S=0×10+½×3.5×10²

S=0+35×5

S=175 m

Hope it helps...

Answer 2

Answer:

175m

Explanation:

Acceleration = 7/2 m/s^2

Initial velocity = 0m/s

Time taken = 10s

By applying,

S = ut + 1/2 at^2

S = 0 + 1/2 × 7/2 × 10^2

S = 7/4 × 100

S = 7 × 25

S = 175m
