The average speed will be:
Total distance travelled divided by time taken
Total distance (in metres)= 80+125+45=250
Total time (minutes) =10
250/10
=25
Thus Mary's average speed is 25 metres per minute.
Answer:
joules = newtons x meters
Explanation:
Work is equal to the force that is exerted, multiplied by the distance over which it is exerted.
In equation form:
joules (work) = newtons (force) x meters (distance) ,
A joule is the unit of work.
Hope this helped!! :)
Work done = force * distance moved (in direction of the force)
force= mass* acceleration
force=58.1N
58.1*(5.8*10^4)
=3,369,800 J
