A bowling ball has a mass of 6 kilograms. A person lifts the bowling ball 2 meters above the ground, using a force of about 60

Luba_88 [7]

The amount of work done by the person is equal to 120 Joules.

<u>Given the following data:</u>

Force = 34 Newton.

Displacement = 15 meters.

Mass = 6 kilograms.

To calculate the amount of work done by the person at a total height of 2 meters:

<h3>How to calculate work done.</h3>

In Science, work done is calculated by multiplying force and the displacement experienced by an object.

Mathematically, work done is given by the formula:

$Work\;done = force \times displacement$

Substituting the given parameters into the formula, we have;

$Work\;done = 60 \times 2$

Work done = 120 Joules.

the initial velocityof a particle along x axis is u at t=0 x=0 and its acceleration is given by a =2x then whats the correct equ

miskamm [114]

Answer:

v² = u² + 2x²

Explanation:

v² = u² + 2as is only valid for constant acceleration. Here, the acceleration is a function of position. We can find the function of velocity by integrating. Acceleration is the derivative of velocity with respect to time:

a = 2x

dv/dt = 2x

Apply chain rule:

dv/dt = dx/dt × dv/dx

dv/dt = v × dv/dx

Therefore:

v dv/dx = 2x

Separate the variables and integrate:

v dv = 2x dx

½ v² |ᵤᵛ = x² |₀ˣ

½ (v² − u²) = x²

v² − u² = 2x²

v² = u² + 2x²

Add these measurements, using significant digit rules:<br><br> 1.0090 cm + 0.02 cm = cm

marin [14]

Answer:

1.029

Explanation:

1.0090 can also be looked at as "1.009"

0.02 can also be looked at as "0.020"

I think of it as 20+9 which is 29. There for your answer should be 1.029. There are no measurement rules applying to this equation since they are both in centimeters. So you don't have to convert anything.
