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?
in order to describe a change in an object's velocity, we have to tell how fast its speed is changing, and in what direction its speed is changing.
that's exactly the information that tells the object's acceleration.
he traveled 24 kilometers. that is his distance traveled. plz mark brainliest
b. ke depends on motion and pe depends on position.
the answer is 1.656372605 newtons.
