There was a collision of a truck weighing 5 tons and a passenger car weighing 1.1 tons.

There was a collision of a truck weighing 5 tons and a passenger car weighing 1.1 tons. The truck got an acceleration of 4 m / s ^ 2. With what acceleration did the passenger car move after the collision?

Data: m1 (truck weight) = 5 t = 5000 kg; m2 (mass of a passenger car) = 1.1 t = 1100 kg; a1 (the acceleration with which the truck began to move after the collision) = 4 m / s2.

The acceleration with which a passenger car will move after a collision is determined from the equality (Newton’s third law): | F1 | = | F2 | = m1 * a1 = m2 * a2, whence a2 = m1 * a1 / m2.

Let’s perform the calculation: a2 = 5000 * 4/1100 = 18.18 m / s2.

Answer: After the collision, the passenger car will move with an acceleration of 18.18 m / s2.
