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 ?

Text Solution

Verified by Experts

Airplane : Change in velocity = 5km/h = `5xx5/18=25/18m//sec`.
Time = 10 sec.
Acceleration = `(25/18)/10=25/18xx1/10=5/36=0.138m//sec^(2)`
Skateboard : Change in velocity = 5 km/h = `25/18m//sec`
Time = 1 sec.
Acceleration = `(25/18)/1=25/18=1.38m//sec^(2)`
`therefore` Skateboard has greater acceleration.
