A 10248 kg car is pulled by a low tow truck that has an acceleration of 2.0m/s what is the net force on the car
Ksenya-84 [330]

Answer: 20496N

Explanation:

The formula to calculate the net force will be given as:

Net force = Acceleration × Mass

Since 10248 kg car is pulled by a low tow truck that has an acceleration of 2.0m/s, the net force would be:

= 10248 × 2

= 20496N

A capacitor is charged to a potential difference of 12v it delivers 40% of its stored energy to a lamp what is the final potenti
Korolek [52]
Call the capacitance C. 
<span>Note the energy in a capacitor with voltage V is E =½CV². </span>

<span>Initial energy = ½C(12)² = 72C </span>

<span>40% of energy is delivered, so 60% remains.in the capacitor. </span>
<span>Remaining energy = (60/100) x 72C =43.2C </span>

<span>If the final potential difference is X, the energy stored is ½CX² </span>
<span>½CX² = 43.2C </span>
<span>X² = 2 x 43.2 = 86.4 </span>
<span>X = 9.3V</span>

A car moving at a speed of 20m/s has a kinetic energy of 300,000 J what’s the cars mass
Alexxx [7]

Answer:

<h2>1500 kg</h2>

Explanation:

The mass of the car can be found by using the formula

m =  \frac{2k}{ {v}^{2} }  \\

From the question we have

m =  \frac{2 \times 300000}{ {20}^{2} }  =  \frac{600000}{400}  =  \frac{6000}{4}  \\

We have the final answer as

<h3>1500 kg</h3>

Hope this helps you
