2.4 IB Momentum and Impulse

Newton's third law state that for every action there is a force that is

• equal in the same direction

• unequal in the same direction

• equal in the opposite direction

• unequal in the opposite direction

In the equation p = mv

• p=impulse

• p=force

• p=acceleration

• p=momentum

The Law of conservation of momentum states that if interacting objects in a system are not acted on by outside forces, the total amount of momentum in the system

• can not change

• will change according to the mass

• can change only if the force remains constant

• can not change if there is acceleration

Give your Answer in m/s with only 2SF - NO Unit

Now, we know that the collision is inelastic, how much energy has been lost - Type your answer 2 SF with the Unit

Calculate the velocity of the Truck after the collision - type the answer in m/s - do NOT type units

Answer the question 3 SF + units
