Answer:
It takes 6.52 s to complete the 150 m track.
Explanation:
Let's find the position of the cyclist during the acceleration.
Now, the final speed at this distance will be:
Now, we know that x(tot) = 150 m, the remaining part will be:
Therefore, the time is:
I hope it helps you!
Answer:
Explanation:
From the question we are told that:
Mass
Initial Velocity
Final Velocity
Generally the equation for Work-done is mathematically given by
W=\triangle K.E
Therefore
Answer:
A. Power incident on panel = 3000W
B. Electrical power generated = 600W
Explanation:
Actual solar intensity I = 750W/m2
A) if area A of panel = 4m2, then,
Power incident on panel = I x A
P = 750 x 4 = 3000W
B) if panel efficiency is 20%,
Then,
Power generates = 0.2 x 3000 = 600W of electricity.
At the top, the the acceleration would be zero
