The carton lies on a plane tilted at an angle of 22.0 degrees to the horizontal with uk= 0.12.

a.) Determine the acceleration of the carton as it slides down the plane.

b.) IF the carton starts from rest 9.30 m up the plane from its base, what will be the carton's speed when it reaches the bottom of the incline.

A descent vehicle landing on Mars has a vertical velocity toward the surface of Mars of 5.5m/s. At the same time, it has a horizontal velocity of 3.5m/s.

a. At what speed does the vehicle move along its descent path?
b. At what angle with the verticle is this path?

Please help me.
I don't understand how to figure this problem out.

Show each step you used. I don't understand how this problem works. Please do not use the pythagorean theorem, use trig functions instead.

Today I took a photo of a park landscape. The moon rising in the background. When looking at the scene thru my specticles, the moon was the size of a dinner plate. My specs are 3x mag. I took a digital photo using a 3x mag lens. The moon was now a pin prick, in relation to the landscape when viewed on the digicam LCD. The digi cam sensor is 3000x2000pics.. Why does the camera lie? What causes the disparity of moon size between my eye and the camera?

are suspended by a pulley with a radius of 4.9 cm and mass of 6 kg. Cord is negligible in mass, pulley rotates witout slipping or friction. The masses start from rest 4 m apart (on is higher than the other), the pulley is a uniform disk. Acceleration of gravity = 9.8 m/s^2.

Calculate the speeds of the two masses as they pass each other in units of m/s.

A fuse melts if the current in a circuit becomes too high, breaking the circuit. However, what I do not understand is the actual purpose of the fuse. What would happen if there was no fuse and the current got too high, what risk is there that the fuse decreases? Also, when the fuse melts, does that mean the wire melts also, and if it does, do you simply replace it with another wire? Please explain well

In attempting to pass the puck to a teammate, a hockey player gives it an initial speed of 2.2 m/s. However, this speed is inadequate to compensate for the kinetic friction between the puck and the ice. As a result, the puck travels only one-half the distance between the players before sliding to a halt. What minimum initial speed should the puck have been given so that it reached the teammate, assuming that the same force of kinetic friction acted on the puck everywhere between the two players?

Hey. My experiment is calculating the work done on different materials, I have obtained different results for the work done for each material. However the problem is, what is the ideal amount of work done in certain senario's? Is there a problem with too much or too little work done, which is my real question. Any help seriously appreciated.
