Please help! Due in 10 min! Please show work! Davien and Jackson are headed to a beach that is 50km from school. At noon, Davien leaves his house that is 10 km closer to the beach than the school is and moves at 40 km/h. Jackson starts from school at 12:30 P. M. and moves at 100 km/h. What time does Davien reach the beach? *

They both arrive at 1:00 PM

Explanation:

Amount Davien has to drive : 40km

Amount Jackson has to drive = 50km

Davien moves at 40km/h,

Therefore, it only takes Davien 1 hour to get there.

12:00 PM + 1 hour = 1:00 PM

Jackson moves 100km/h

He needs to drive 50 min, so 50/100 = 1/2

It takes him half an hour, or 30minutes

If he leaves at 12:30, then he gets there at 1:00 PM

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.
