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>.

A 5.45-g combustible sample is burned in a calorimeter. the heat generated changes the temperature of 555 g of water from 20.5°c

Y_Kistochka [10]

Given:
m = 555 g, the mass of water in the calorimeter
ΔT = 39.5 - 20.5 = 19 °C, temperature change
c = 4.18 J/(°C-g), specific heat of water

Assume that all generated heat goes into heating the water.
Then the energy released is
Q = mcΔT
= (555 g)*(4.18 J/(°C-g)*(19 °C)
= 44,078.1 J
= 44,100 J (approximately)

Answer: 44,100 J
