The Moon is about 3.8 x 108 m from Earth. Traveling at the speed of light, 3.0 x 108 m/s, how long does it take a laser beam to go from Earth to the Moon and back again?
The following conversion equivalents are given:1 mile = 5280 ft 1 ft = 12 in 1 m = 39.37 in 1 hour = 60 min 1 min = 60 sA particle has a velocity of 4.7 miles per hour. The velocity, in m/s, is closest to:A) 2.1 B) 1.7 C) 1.9 D) 2.3 E) 2.5
A student solving a physics problem for the velocity of an object has applied appropriate physics principles and obtained the expression v=d/t−v0, where d=35.0meter, t=9.00second, and v0 =3.00meter/second. What is the velocity v?
