Help please it’s urgent A fisherman notices that one wave passes the bow of his anchored boat
every 3 seconds. He measured the wavelength to be 8.5 meters. How fast
are the waves traveling?

1.)2.83m/s
2.)0.283m/s
3.)28.3m/s

we need to know the time interval during which the force acts. impulse of force = momentum change

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.
