A block with a mass of 3.0 kg is held against a spring with a spring constant of 550 N/m. The block compresses the spring 28 cm from an equilibrium position. After the block is released, it travels along a frictionless surface and then up a ramp with a coefficient of friction of 0.15 for 1.0 m. If the inclination of the ramp is 25 degrees calculate a) the launch speed from the ramp b) maximum height and c) distance from the ramp when the mass makes first impact with the surface.

gpe = mass x gravity constant x height or… gpe = mgh

where… mass: measured in kilograms (kg)

gravity: gravity constant on earth = 10.00 m/s2

height: measured in meters (m)

gpe: measured in joules (j) or kilojoules (kj)

how do you solve gpe?

gravitational potential energy (gpe) is the energy an object has because of its position above the. ground.

gpe = mass x gravity constant x height or… gpe = mgh.

the moving of the box is a result of centripetal force. think of that  as a car or a truck in this case creates a turn, the force of friction performing upon the turned wheels of the car runs centripetal force obligatory for circular motion for the things inside it.
