Question

α∞Which has the greater acceleration, an airplane, that goes from 1000 km/h to 1005 km/h in 10s or a skateboard that goes from zero to 5km/h in 1 second?

Answer 1

Answer:

Skateboard

Explanation:

Given :

• An aeroplane goes from 1000 km/h to 1005 km/h in 10 seconds

• A skateboard accelerates from 0 km/h to 5 km/h in 1 second

To find :

• Which of them has a greater acceleration

Acceleration of aeroplane :

(v-u) / t

(1005-1000)/10

5/10

0.5 km/s²

Acceleration of skateboard :

(v-u) / t

(5-0)/1

5 km/s²

Hence the acceleration of the skateboard is more than that of aeroplane by 10 times

Skateboard
