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.

what experimental evidence led scientists to change from the previous model to this one?

a few of the positive particles aimed at a gold foil seemed to bounce back.

the colors of light emitted from heated atoms had very specific energies.

experiments with water vapor showed that elements combine in specific proportions.

cathode rays were bent in the same way whenever a magnet was brought near them.

that would be because of both gravity and friction. so     c
