Ethics Applied
I have to watch a movie of my choice and then write a paper consisting of 4-5 paragraphs about 2 characters and a major moral issue they each face and then identify the moral approach (egoism, religious ethics, and contractarianism) each uses to resolve the issue. I need help ...

. In the annual walkathon, Lee jogs for 5 3/4 miles more than he walks. If he travelled a total of 15 miles, how many miles did he walk?

physics
A 6kg cat is running across a table which is 1.2 m tall. The kinetic energy of the cat is 48 j. A) how fast is the cat running? B) what is the potential energy of the cat? C) what is the total mechanical energy of the cat?

physics
A ball is thrown upward at a speed v0 at an angle of 52.0˚ above the horizontal. It reaches a maximum height of 7.3 m. How high would this ball go if it were thrown straight upward at speed v0?

physics
A 2490 kg demolition ball swings at the end of a 35.9 m cable on the arc of a vertical circle. At the lowest point of the swing, the ball is moving at a speed of 7.26 m/s. Determine the tension in the cable.

physics
Boat A negotiates a curve whose radius is 336 m. Boat B negotiates a curve whose radius is 160 m. Each boat experiences the same centripetal acceleration. What is the ratio of the speed of boat A to that of boat B?

Physics
A jet flying at 120 m/s banks to make a horizontal circular turn. The radius of the turn is 3810 m, and the mass of the jet is 2.19 × 105 kg. Calculate the magnitude of the necessary lifting force. L =____ N

physics
A car (m = 1540 kg) is parked on a road that rises 18.9 ° above the horizontal. What are the magnitudes of (a) the normal force and (b) the static frictional force that the ground exerts on the tires?

physics
A golfer hits a shot to a green that is elevated 3.0 m above the point where the ball is struck. The ball leaves the club at a speed of 19.4 m/s at an angle of 45.0˚ above the horizontal. It rises to its maximum height and then falls down to the green. Ignoring air resist...
