To successfully escape a planet's gravity, a space ship must achieve escape velocity, which for Earth is 11.2 km/s or 25,054 miles per hour. If a ship reaches this speed and maintains it, then neglecting the need to slow down prior to landing, how long would it take the ship to reach the Moon? Use the actual distance to the Moon of 233,815 miles and give your answer in hours.

Poltergeist

Answer:

9.33 Hours.

Step-by-step explanation:

The time in hours is given by the distance divided by velocity.

[tex]t=D/v[/tex]

Now we are told that the velocity of the ship will be 25054 miles per hour, and the distance to the Moon is 233815 miles; therefore the time it will take the spacecraft to reach the moon will be:

[tex]t=233815miles/(25054miles/hr) = 9.33 hours[/tex]
