George works for a moving company. He is
paid $1 for every 1,000 Newton-meters of
work. On Thursday, George used 600 Newtons
of force moving a piano 80 meters. It took him
50 minutes to move the piano. How much
should George get paid? How fast did he move
the piano on average?

What is the acceleration of a spaceship that is initially at rest and then speeds up to 220 m/s in 20 seconds

Amass attached to a spring is displaced from its equilibrium position by 5cm and released. the system then oscillates in simple harmonic motion with a period of 1s. if that same mass–spring system is displaced from equilibrium by 10cm instead, what will its period be in this case? a mass attached to a spring is displaced from its equilibrium position by and released. the system then oscillates in simple harmonic motion with a period of . if that same mass–spring system is displaced from equilibrium by instead, what will its period be in this case? a) 0.5sb) 2sc) 1sd) 1.4s

Aball thrown by ginger is moving upward through the air. diagram a shows a box with a downward arrow. diagram b shows a box with an upward arrow. diagram c shows a box with a downward and upward arrow equal in size. diagram d shows a box with a downward and upward arrow with the downward arrow larger in size. which force diagram represents the forces on the ball? you may neglect the effects of air resistance.
