4. A car with a mass of 2,200 kg can accelerate from 0 to 30 m/s in 6 seconds.
wlad13 [49]

Answer:

The engine generates a force of 11000 Newtons.

Explanation:

To determine the force, first you will need to calculate the acceleration. Acceleration is change in velocity over change in time, so in this case:

a = \frac{\Delta v}{\Delta t}=\frac{(30-0)\frac{m}{s}}{(6 - 0 )s}=5 \frac{m}{s^2}

Force is then determined as

F=ma = 2200kg\cdot 5\frac{m}{s^2}=11000N

This is the forward force, i.a. one acting in the direction of the car's acceleration. we are told that there is no inefficiency in the engine and transmission, therefore this same force is generated by the engine.

The acceleration of an object increases by the force applied to it and decreases based on it's mass.
xenn [34]

Explanation:

Force is defined as mass times acceleration.

Mathematically,          F = m × a

where             F = force

                       m = mass

                       a = acceleration

This shows that force is directly proportional to acceleration. So, when greater force is applied then acceleration will also increase.

Whereas acceleration is inversely proportional to mass. So, when there is increase in mass then there will be decrease in acceleration.
