Beth, a construction worker, attempts to pull a stake out of the ground by pulling on a rope
that is attached to the stake. The rope makes
an angle of 48.4
◦ with the horizontal.
If Beth exerts a force of 131.1 N on the
rope, what is the magnitude of the upward
component of the force acting on the stake?
Answer in units of N.

How many neutrons does element x if it’s atomic number is 28 and its mass number is 87

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.
