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.

  distance on the y-axis and time on the x-axis.

explanation:

the instantaneous velocity = change in position/time taken

the slope of the graph should give instantaneous velocity.

  slope of a graph = change in value of y -axis / change in values of x -axis

  comparing both the equations

    change in value of y -axis = change in position

  change in values of x -axis = time taken

so position values should be on the y axis and time values should be on the x axis.

distance on the y-axis and time on the x-axis.
