Question

a spacecraft covers the last straight stretch of an inter-galactic space race in 2.5 days. During that time, it uses its hyper-drive and speeds up from 65,640 km / h to 120,600 km / h. What acceleration does the hyperdrive allow for?

Answer 1

`a=916\ km/h^2`

Step-by-step explanation:

Given that,

Initial speed, u = 65,640 km/h

Final speed, v = 120,600 km/h

Time, t = 2.5 days = 60 h

We need to find the acceleration of the hyperdrive. We know that, acceleration is equal to the change in velocity per unit time. So,

`a=(v-u)/(t)\\\\a=(120,600-65,640 )/(60)\\\\=916\ km/h^2`

So, the acceleration of the hyperdrive is equal to
`916\ km/h^2`.
