What is the change in momentum of a 40 kg runner that travels from 5 m/s to 11 m/s

Physics

p=mv where p is momentum in kgms-1, m is mass/kg and v is velocity/ms-1

Therefore to find the change in momentum we can just substitute the numbers in and find the difference.

At 5ms-1 the runner has a momentum of 5*40=200kgm/s
At 11ms-1 the runner has a momentum of 11*40=440kgm/s

Finding the difference, the change of momentum is 240kgm/s

Light, dry snow is called powder. Skiing on a powder day is different than skiing on a day when the snow is wet and heavy. When
kramer

Answer:

Explanation:

Given:

- Acceleration a_dry = 0.4*a_wet

- initial velocity V_i

Find:

By how much does time taken to stop of dry snow differ from time taken to stop on wet snow?

Solution:

- Time taken to stop on wet snow t_wet:

                            V_f = V_i + a_wet * t_wet

                             t_wet = - a_wet / V_i

- Time taken to stop on wet snow t_wet:

                             V_f = V_i + a_dry * t_dry

                             t_dry = - a_dry / V_i

- Difference in t_wet and t_dry:

                             t_dry - t_wet =  - a_dry / V_i  + a_wet / V_i

                             dt = (a_wet - a_dry) / V_i

                             dt = (a_wet - 0.4*a_wet) V_i

                             dt = 0.6*a_wet / V_i
