Answer:
48.5 hp
Explanation:
= mass of the car = 1200 kg
= initial speed of the car = 25 km/hr = 6.94 m/s
= final speed of the car = 100 km/hr = 27.78 m/s
= time interval = 12 s
Power output of the engine is given as
W
we know that , 1 hp = 746 W
hp

Explanation:
Sorry this took so long it was a bit hard to remeber at first but I got it :)
Mark me as branliest if it is correct
Answer:
A fundamental quantity is something that can only be found by measuring, such as measuring the length of a pencil. We have no other way to find out the length of the pencil other than measuring it in some way.
A derived quantity is something that is calculated and that is not measured <em>directly. </em>Area is found by multiplying two lengths together. We cant find the area other than computing it somehow
That depends on the weight, shape, size, density, and moisture content
of the cotton ball, as well as on the length, shape, thickness, and surface
texture of every little cotton fiber sticking out of it.
Now you know why we typically ignore air resistance when we work with
objects falling in gravity.
