The expanded form of (x-2y)whole square is xto the power 2 -4ywhole square-4yx. Is the given statement correct? Justify.​

Answer 1

Answer:

Given:-

Mass of automobile (m) = 1500 kg.

Acceleration (a) = –1.7 ms^{–2}

–2

To find:-

Force between the vehicle and the road

Solution:-

We know that,

Force (f) = ma

= (1500 kg) (–1.7 ms)^{–2}

–2

= –2550 N.

Thus, force between the vehicle and the road if the vehicle is to be stopped with a negative acceleration of 1.7 ms^{–2}

–2

is –2550 N.
