A small glider is placed against acompressed spring at the bottom of an air track that slopes upwardat an angle of 33.0 degrees above the horizontal. The glider has mass 7.00×10−2 kg. The spring has600 N/m and negligible mass. When the spring is released, the glider travels a maximum distance of 1.30 m along the airtrack before sliding back down. Before reaching this maximum distance, the glider loses contact with the spring.
A] What distance was the spring originallycompressed?B] When the glider has traveled along the airtrack 0.300 m from its initial position against the compressedspring, is it still in contact with the spring?C] What is the kinetic energy of the gliderat this point?
A 66-g ice cube at 0°C is placed in 865 g of water at 26°C. What is the final temperature of the mixture
Starting from rest, a 6.00-kg block slides 3.00 m down a rough 30.0° incline. The coefficient of kinetic friction between the block and the incline is ?k = 0.436. Determine the work done by the force of gravity
A sports car moving at constant speed travels 90 m in 4.9s. If it then brakes and comes to a stop in 4s, what is its acceleration? Express the answer in terms of g's, where g = 9.80 m/s2. (Take the positive direction to be direction of travel.)
Vector A has a magnitude of 10m and makes an angle of 78o with the positive x axis. Vector B also has a magnitude of 13m and is directed along the negative x axis. Enter your answers in distance then angle (in degrees).
