Question

for how long a time must tow truck pull with a force of 550N on a stalled 1200kg car to give a forward velocity of 2.0m/s

Answer 1

Here, F=550 N

m=1200 kg

u=0, v=2m/s

a=v-u/t

a=2/t

Since, F=ma

550=1200(2/t)

So, t=4.36 seconds

Answer 2

Answer:

The answer is 4.36 seconds

According to Newton's second law, an object's acceleration caused by a net force is directly proportional to the force's magnitude, moving in that direction as the force, and inversely proportional to its mass of the item.

Explanation:

The thorough description of how a force can alter a body's motion is given by Newton ’s 2nd law. According to this, a body's velocity changes at a rate equal to a force acting on it over time in both speed and phase.

Force is $550N$

The car weighs $1200 kg$

The car's speed is $2.0 m/s$

We must determine when the car must be pulled by the tow track. the second law of motion, Newton

$F=\frac{mv}{t}$, where M is the mass, V is the velocity, and Time t, is the impulse force.

Modifying the formula

$t=\frac{mv}{F}$

Thus;

$Time=\frac{(1200kg*2.0m/s^{2} )}{550N}$

         $=4.36 seconds$

Therefore, it takes 4.36 seconds to draw the car.
