Answer:
53.3 N force acting on the cart.
Explanation:
<u><em>Given data</em></u><u>:</u>
Weight/Mass: 20kg
Initial speed (Vi): 2 m/s
Final speed (Vf) : 10m/s
time: 3 seconds
Force:?
<em><u>Formula:</u></em>
F: (Mass) x (accerlation)
F= m x a
Vf = Vi + at
a = Vf - Vi / t
a = (10m/s) -(2m/s) / 3s
a = (8m/s) / 3s
a= 2.6 m/s^2
F = m x a
F = 20kg x 2.6 m/s^2
F = 53.3 N
It is @ intensity, the others do. or male sense for this question
They both store energy but lipids are long term storage while carbohydrates are short term which means they get burnt first and then the lipids are used.
