Force required to accelerate 10 kg object to 5.9 m/s/s ?
Mass = 10 kg
Acceleration = 5.9 m/s^2
Force = Mass * Acceleration
Force = 10 kg * 5.9 m/s^2
Force = 59 kg m /s^2 = 59 N
Acceleration is the simply rate of change in velocity, how much faster or slower is the object changing speed with respect to time.
A = v/t = 5 km/hr/0.5 hr
5/1/2 = 5 • 2 = 10 km/hr^2.
This would be the acceleration.
(a) 8927 mi/h
In order to calculate the average speed, we need to convert the time (t=5.0 y) into hours first. In 1 year, we have 365 days, each day consisting of 24 hours, so the time taken is:

The distance covered by the spacecraft is

Therefore, the average speed is just the ratio between the distance covered and the time taken:

(b) 35 minutes (2097 seconds)
The transmitted signals (which is a radio wave, which is an electromagnetic wave) travels back to the Earth at the speed of light:

Since 1 miles = 1609 metres, the distance covered by the signal is

So, the time taken by the signal will be

And since 1 minute = 60 sec, the time taken is
