a truck of mass 150kg is released from rest at point A and moves along a frictionless truck as shown below

Vmax = 34.3[m/s]

Explanation:

We must remember that the definition of energy transformation, which tells us that potential energy is transformed into kinetic energy and vice versa.

Potential energy is defined as the product of mass by gravity by height.

where:

m = mass = 150 [kg]

g = gravity acceleration = 9.81 [m/s²]

h = elevation = 60 [m]

When the height is zero, all the potential energy will have been transformed into kinetic energy, with this kinetic energy we can calculate the velocity.

The maximum kinetic energy is reached in B

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.
