Two charges (+2.00μC) and (+2.00μC) are placed symmetrically along the x-axis at x=±3.00cm. Consider a charge of charge +4.00μC and mass 10.0 mg moving along the y-axis.

If Q3 starts from rest at y=2.00cm, what is its speed when it reaches y=4.00cm?

Explain why you think this diagram shows what happened to the carbon in the biodome.

Aballoon is rising vertically upwards at a velocity of 10m/s. when it is at a height of 45m from the ground, a parachute bails out from it. after 3s he opens his parachute and decelerates ata a constant rate 5m/s. when. (a) what was the height of the parachutist above the ground when he opened his parachute? (b)how far is the parachutist from the balloon at t=3s? (c)with what velocity does the parachutist hit the ground? (d)after how long does the parachutist hit the ground after his exist from the balloon?
