# Ablock with mass m =6.9 kg is hung from a vertical spring. when the mass hangs in equilibrium, the spring stretches x = 0.29 m. while at this equilibrium position, the mass is then given an initial push downward at v = 4.1 m/s. the block oscillates on the spring without friction. 1)what is the spring constant of the spring? 2)what is the oscillation frequency? 3)after t = 0.42 s what is the speed of the block? 4)what is the magnitude of the maximum acceleration of the block? 5)at t = 0.42 s what is the magnitude of the net force on the block?

Light from the sun reaches the earth in 8.3 minutes. the velocity is 3.00 x 10^8 m/s. how far is earth from the sun? i know how to get to d = (3 x 10^8 m/s)(498 sec). i just don't know how to get from there to the answer being 1.5 x 10^11 m.
