<h3><u>Given</u> :</h3>

Momentum of car = 10880 kg m/s

Velocity of car = 16 m/s

<h3><u>To Find</u> :</h3>

We. have to find mass of the car.

<h3><u>Solution</u> :</h3>

★ Momentum of body is measured as the <u>product of mass and its velocity</u>.

It is a vector quantity having both <u>magnitude</u> as well as <u>direction</u>.

SI unit : kg m/s or N s

Formula : p = m × v

  • p denotes momentum
  • m denotes mass
  • v denotes velocity

★ <u>Calculation</u> :

⭆ p = m × v

⭆ 10880 = m × 16

⭆ m = 10880/16

⭆ m = 680 kg

∴ <u>Mass of the car = 680 kg</u>

Answer:

<h3>The answer is 67.5 kg</h3>

Explanation:

To find the mass of an object given it's momentum and velocity we use the formula

m =  \frac{p}{v}  \\

where

p is the momentum

v is the velocity

From the question

p = 1080 kgm/s

v = 16 m/s

We have

m =  \frac{1080}{16}  =  \frac{135}{2}  \\

We have the final answer as

<h3>67.5 kg</h3>

Hope this helps you

Two men, Joel and Jerry, each pushes an object that are identical on a horizontal frictionless floor starting from rest. Joel an
Nataliya [291]

Answer:

The work done by Joel is greater than the work done by Jerry.

Explanation:

Let suppose that forces are parallel or antiparallel to the direction of motion. Given that Joel and Jerry exert constant forces on the object, the definition of work can be simplified as:

W = F\cdot \Delta s

Where:

W - Work, measured in joules.

F - Force exerted on the object, measured in newtons.

\Delta s - Travelled distance by the object, measured in meters.

During the first 10 minutes, the net work exerted on the object is zero. That is:

W_{net} = W_{Joel} - W_{Jerry}

W_{net} = F\cdot \Delta s - F\cdot \Delta s

W_{net} = (F-F)\cdot \Delta s

W_{net} = 0\cdot \Delta s

W_{net} = 0\,J

In exchange, the net work in the next 5 minutes is the work done by Joel on the object:

W_{net} = W_{Joel}

W_{net} = F\cdot \Delta s

Hence, the work done by Joel is greater than the work done by Jerry.
