A huntress and her dog set off on a trip towards a hut that is 2 km away. The dog races ahead at 4 m/s (twice the speed of the huntress), reaches the hut, turns around and comes back to the her. a)How far along the trail do they first meet? (in metres)

b)After how long do they meet? (in minutes)

c)The dog keeps running back and forth along the trail between the hut and his companion until she arrives at the hut. How far in total does the dog travel? (in metres)

c)as speed changes, wavelength and frequency change.

everything changes!

do you have a formula possibly

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.
