bungee jumpers leap off high cliffs to enjoy the speed gravity gives them. what is the speed of a jumper 10 seconds after jumping

98 m/s.

Explanation:

In this problem, we need to find the speed of a jumper 10 seconds after jumping. Initially, the bungee jumper was at rest. Let v is the speed after 10 s. Using first equation of motion.

v = u +at

Here, u = 0 and a = g

v = gt

v = (9.8 m/s)(10 s)

v = 98 m/s

So, the speed of a jumper 10 seconds after jumping is 98 m/s.

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.

mass = 0.3 kg.

wavelength divides in half and speed stays the same.
