Speed climbing is a sport in which climbers try to scale rocks or walls as quickly as possible. In 2017, Reza Alipour set the speed climbing world record by climbing a 15m wall in 5.48 seconds. Alipour's mass is 76kg. What is the average power he needed to expend in order to achieve his world record?

The average power of the climber is 1.03 kW.

Explanation:

Given that,

Mass of Alipour, m = 76 kg

In 2017, Reza Alipour set the speed climbing world record by climbing a 15 m wall in 5.48 seconds. We need to find the average power he needed to expend in order to achieve his world record.

The rate at which the work is done is called power of an object. It is given by :

W is the work done, W = mgh

or

P = 1.03 kW

So, the average power of the climber is 1.03 kW. Hence, this is the required solution.

the skeletons of most mammals reach a certain size and then stop growing. however, many animals, including some mammals, keep growing throughout their lives. kangaroos, for example, just keep growing and growing until they die. also, the longer an animal lives the greater the chance it might catch some deadly disease.
