You and a friend are moving a very heavy and irregular piece of furniture across a room. You arelifting it to prevent it from scratching your wooden floor. Your friend lets you pick where you aregoing to hold it and your friend will hold it at the other end (or some other place you tell yourfriend to hold it). To make it easier on yourself, you would:A. Hold the end closer to the center of mass (your friend holds the other end).B. Hold the end farther from the center of mass (your friend holds the other end).C. Hold it at the center of mass and have your friend hold it from one of the other ends. D.It doesn't matter where you pick - you'll both have to exert the same force no

What is the acceleration of a spaceship that is initially at rest and then speeds up to 220 m/s in 20 seconds

Give one example to show that when substances are mixed,it may result in a chemical or a physical change depending on the conditions.

Ablock of mass m = 2.5 kg is attached to a spring with spring constant k = 740 n/m. it is initially at rest on an inclined plane that is at an angle of theta= 26 with respect to the horizontal, and the coefficient of kinetic friction between the block and the plane is uk = 0.17. in the initial position, where the spring is compressed by a distance of d = 0.16 m, the mass is at its lowest position and the spring is compressed the maximum amount. take the initial gravitational energy of the block as zero. the block's initial mechanical energy is 9.472 j.b. if the spring pushes the block up the incline, what distance l in meters will the block travel before coming to rest? the spring remains attached to both the block and the fixed wall throughout its motion.
