If it were possible for a rocket to travel at the speed of light (3.0 x 108 m/s), about how long would it take to reach this speed from rest? Assume the rocket accelerates at a rate of 750 m/s2.

Respuesta :

V=at=750t=310^8--->t=400000 secs = 4 days 15 hours 6 minutes and 40 seconds

Answer:

4 x 10^5 s

Explanation:

u = 0

v = 3 x 10^8 m/s

a = 750 m/s^2

Let t be the time taken.

Use first equation of motion

v = u + a t

3 x 10^8 = 0 + 750 x t

t = 4 x 10^5 s
