Answer 1

Answer:

1

Which has the greater acceleration, an airplane that goes from 1,000 km/h to 1,005 km/h in 10 seconds or a skateboard that goes from zero to 5 km/h in 1 second?

1000 kph=1000000 m/hr

=277.7778 m/s

1005 kph=1005000 m/hr

=279.1666667 m/s

v=u+at

279.1666666667=277.7777778 m/s+10a

10a=1.3888888888

a=0.13888888888 m/s² acceleration

5 km/h=1.38888888888888 m/s

1.38888888888888=0+1a

a=1.38888888888888 m/s²

The skateboard’s acceleration is greater by a factor of 10 ………………..

Now please mark me
