<span>6160 joules

to lift 1 newton 1 metre requires 1 joule
there are 10 newtons in one kilo

so 77(kg) x 8 (metres) x 10 (newtons/kilo) = 6160 joules</span>

What net force would be required for a 50.5 kg wolf to accelerate at 5.0 m/s^2

Basile [38]

Answer:

$\boxed {\boxed {\sf 252.5 \ Newtons }}$

Explanation:

Force is the push or pull on object that can cause different things, like acceleration. According to Newton's 2nd Law of Motion, it is the product of mass and acceleration.

$F=m*a$

The mass of the wolf is 50.5 kilograms and the acceleration is 5.0 meters per square second. Therefore:

$m= 50.5 \ kg$

$a= 5.0 \ m/s^2$

Substitute the values into the formula.

$F= 50.5 \ kg * 5.0 \ m/s^2$

Multiply.

$F=252.5 \ kg*m/s^2$

1 kilogram meter per square second is equal to 1 Newton.
Our answer of 252.5 kg*m/s² is equal to 252.5 Newtons.

$F= 252.5 \ N$

The force required is <u>252.5 Newtons</u>.
