1. what is the net force required to give an automobile with a mass of 1,600 kg an acceleration of 4.5 m/s²?
2. what is the acceleration of a wagon with a mass of 22 kg if a horizontal force of 64 n is applied to it?
3. what is the mass of an object that is experiencing a net force of 200 n and an acceleration of 500 m/s²?
4. if a truck has a mass of 2,000 kilograms and a velocity of 35 m/s, what is its momentum?
5. an 8 - kilogram bowling ball is rolling in a straight line toward you. if its momentum is 16 kg*m/s, how fast is it traveling?
6. a beach ball is rolling in a straight line toward you at a speed of 0.5 m/s. its momentum is 0.25 kg*m/s. what is the mass of the beach ball?
7. how much does a 990 kg car weigh?
8. a bicycle takes 8.0 seconds to accelerate at a constant rate from rest to a speed of 4.0 m/s. if the mass of the bicycle and rider together is 85 kg, what is the net force acting on the bicycle? (hint: calculate acceleration!)
9. rank the following objects from least inertia to most inertia. baseball small car truck feather large train
10. rank the following objects from least momentum to most momentum. fast car parked truck slow car fast baseball fast feather

Explanation:

Step1: Identify the formula

Newton's second law \(F = ma\), where \(F\) is force, \(m\) is mass, and \(a\) is acceleration.

Step2: Substitute the values

Given \(m = 1600\space kg\) and \(a=4.5\space m/s^{2}\), substitute into the formula: \(F=(1600)(4.5)\)

Step3: Calculate the result

\(F = 7200\space N\)

Answer:

\(7200\space N\)
