If you were in a spaceship and fired a 1000kg probe into frictionless space, how much force would have to be exerted on the probe to keep it going for 1000 years?

Which fators influence ocean currents

Ablock of mass 1.5 kg slides down an inclined plane that has an angle of 15. if the inclined plane has no friction and the block starts at a height of 3 m, how much kinetic energy does the block have when it reaches the bottom? acceleration due to gravity is g = 9.8 m/s2. a. 6.8 j b. 50.9 j c. 0 j d. 44.1 j
