Motion questions...
Need a little help...
If the sun is a distance of 1.5 x 10^8 km from earth, how long does it take sunlight to reach Earth if it moves at 3.0 X 10^8 m/s?
A rocket moves through out space at 11,000 m/s. At this rate how much time would be required to travel the distance from the Earth to Moon, which is 38,000 Km?
A rifle is fired straight up, the bullet leaves the rifle with an initial velocity magnitude of 724 m/s. After 5.000 s the velocity is 675 m/s. At what rate is the bullet decelerated?
THX
