A 10000 N car comes to a bridge during a storm and finds the bridge washed out. The 750N driver must get to the other side, so he decides to try leaping it with his car. The side the car is on is 23.2m above the river, while the opposite side is a mere 6.20m above the river. The river itself is a raging torrent 65.0m wide.
How fast should the car be traveling just as it leaves the cliff in order to clear the river and land safely on the opposite side?
What is the speed of the car just before it lands safely on the other side?
Determine the direction of the net electrostatic force on charge q3 (angle with respect to the positive x-axis).
Small telescopes are often advertised as "200 power" or "magnifies 200 times." As someone knowledgeable about astronomical telescopes, how would you progress such advertisements.
