Question 1:

Very Easy

Imagine a car with a mass of 1200 kg moving at a speed of 20 m/s. Considering the formula Q = m * v, where Q is the momentum, m is the mass, and v is the velocity, calculate the momentum of the car.

Question 2:

Medium

Pedro and Joana are playing with toy cars on a flat and horizontal surface. Pedro pushes a 500 g car at a speed of 2 m/s, while Joana pushes another 300 g car at a speed of 3 m/s. a) Calculate the momentum of each car. b) If the two cars collide and stick together, what will be the total momentum of the system formed by the two cars? c) What will be the speed of the cars after the collision?

Question 3:

Very Easy

A student of experimental physics is conducting a practical experiment where he pushes a 2 kg cart on a horizontal table with a constant force of 10 N for 5 seconds. Considering that the cart is initially at rest and neglecting any effects of friction or air resistance, determine the momentum acquired by the cart at the end of the 5 seconds of force application.

Question 4:

Medium

An object of mass m is moving with velocity v in one direction collides with a second object of mass M that is initially at rest. After the collision, the first object starts moving in a new direction, maintaining the same velocity v. Which of the following alternatives is correct about the total momentum of the system?

Question 5:

Easy

A car weighing 1500 kg is stopped at a traffic light. When the light turns green, it starts moving and reaches a speed of 10 m/s after 5 seconds. Calculate the momentum of the car after the 5 seconds, using the formula Q = m * v, where Q is the momentum, m is the mass of the car, and v is the velocity of the car.
