1) Friction is exerted between a surface and a contacting object. Derive an equation for us, the coefficient of static friction, in terms of O, the angle of elevation of an incline, and physical
constants.

In physics the desire of an object to keep doing what it is doing is termed?

The slope of a velocity time graph over any interval of time gives the during that interval

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.
