<em>Hello, </em>
<h3><u>QUESTION)</u></h3>
<em>✔ We have Ek = 1/2m x v² </em>
- Ek = 1/2 x 79.8 x 16²
- Ek = 10 214.4 J
In order to come to a complete stop, the cyclist must convert all his kinetic energy into thermal energy. Given that the braking force opposes movement, the work is therefore resistant, i.e. W = -10 214.4 J.
D, you wanna know why.... cause I looked it up
Around 8 hours and 20 minutes
Explanation:
I divided 500 by 60 and got 8.3333333333 and i round it up to 8.20, so it is 8 hours and 20 minutes.
Answer:
Explanation:
v= u + at
v is final velocity , u is initial velocity . a is acceleration and t is time
Initial velocity u = 0 . Putting the given values in the equation
v = 0 + g sin 18 x 3.5
= 10.6 m /s
