<span>Answer:
For the old car:-
By v = u + at
=>v = 0 + 10a
=>a = v/10 m/s^2
By s = ut + 1/2at^2
=>s = 0 + 1/2 x v/10 x 10 x 10 = 5v
Thus F = ma
=>F = m x v/10 = mv/10
=>P(old) = F x s = mv/10 x 5v = 1/2mv^2 ------------------------(i)
For new car:-
By v = u + at
=>6v = 0 + 10a
=>a = 3/5v
By s = ut + 1/2at^2
=>s = 0 + 1/2 x 3/5v x 10 x 10
=>s = 30v
By F = ma
=>F = m x 3/5v = 3mv/5
Thus P(new) = F x s = 3mv/5 x 30v = 18mv^2 ------------------------------(ii)
=>P(new) : P(old) = 18mv^2 : 1/2mv^2 = 36 : 1</span>
Well, you can turn these into percents to get a different view if the fraction thing is messing you up. Do this by dividing the top by the bottom and multiplying bu 100.
1/8 = 0.125 0.125 x 100 = 12.5%
3/8 = 0.375 0.375 x 100 = 37.5%
1/4 = 0.25 0.25 x 100 = 25%
1/8 is the smallest and 3/8 is the largest
Another way to do this would be to multiply 1/4 so all three numbers have equal denominatior.
1/4 x 2/2 = 2/8
comparing, 2/8 3/8 and 1/8, you can see that 1/8 is the least and 3/8 is the most
Good evening/morning, today im going to talk about my birthday gifts, everyone knows what a birthday is right?, well if you dont, im here to help you, a birthday is the anniversary of the day on which a person was born, typically treated as an occasion for celebration and the giving of gifts. so, naturally, my family congratulated me and gave me tons of gifts, and some I will be donating, anyways, back to the point, my parents gave me a new phone, I need that, so i was very happy that they got that for me in my birthday.
hope this helps!
