What is the formula for calculating mechanical power

Oksi-84 [34.3K]

Answer:

Because work can be defined as force time distance, we can also use the following equation

Solution

P=power (w or ft-lbf/s)

F=force (N or lbf)

D=distance (m or ft)

T=time (sec)

One horsepower is equivalent to 550 ft-lbf/s and 745.7 watts.

Force (N) = 250<br> Mass (kg) = 221<br> Acceleration (m/s^2) = ?

lyudmila [28]

Answer:

The required acceleration is $a=1.1$ m/s²

Explanation:

Given

Force F = 250 N

Mass m = 221 kg

To determine

Acceleration a = ?

We know that acceleration is produced when a force is applied to a body.

The acceleration can be determined using the formula

$F = ma$

where

F is the force

m is the mass

a is the acceleration

now substituting F = 250 , and m = 221 in the formula

$F = ma$

$250 = 221 (a)$

switch the equation

$221(a) = 250$

Divide both sides by 221

$\frac{221a}{221}=\frac{250}{221}$

simplify

$a=\frac{250}{221}$

$a=1.1$ m/s²

Therefore, the required acceleration is $a=1.1$ m/s²

A car has a speed of 12m/s. The mass of the car and its passengers is 1250 kg. What is the total momentum of the car/passengers?

Temka [501]

Answer:

15000kgm/s

Explanation:

Given parameters:

Speed of the car = 12m/s

Mass of car and passengers = 1250Kg

Unknown:

Momentum of the car = ?

Solution:

Momentum is the quantity of motion a body posses;

Momentum = mass x velocity

Now insert the given parameters and solve;

Momentum = 12 x 1250 = 15000kgm/s
