Question

1.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?
2.A beach ball is rolling in a straight line toward you at a speed of 0.5 m/sec. Its momentum is 0.25 kg•m/s. What is the mass of the beach ball?
3.A 4,000-kilogram truck travels in a straight line at 10.0 m/s. What is its momentum?
Momentum = (mass) x (speed) = (4,000) x (10) = 40,000 kilogram-meters/second
4.A 1,400-kilogram car is also traveling in a straight line. Its momentum is equal to that of the truck in the previous question. What is the velocity of the car?
5.Which would take more force to stop in 10 seconds: an 8.0-kilogram ball rolling in a straight line at a speed of 0.2 m/s or a 4.0-kilogram ball rolling along the same path at a speed of 1.0 m/s?
6.The momentum of a car traveling in a straight line at 20 m/s is 24,500 kg•m/s. What is the car’s mass?
7.Another pitcher throws the same baseball in a straight line. Its momentum is 2.1 kg•m/s. What is the velocity of the ball?
8 A 1-kilogram turtle crawls in a straight line at a speed of 0.01 m/s. What is the turtle’s momentum?

Answer 1

Well, Brainly is a site established for the purpose of getting HELP
with homework.  That doesn't mean that you just dump your whole
assignment here and wait for somebody to give you all the answers.

Especially when you're only offering 5 points for 8 problems.

And especially when all 8 problems are exactly the same problem,
only with different numbers. 


This whole sheet deals with linear momentum.
The momentum of a moving object is (its mass) x (its speed).

Now you have the formula for momentum:

                                  Momentum = (mass) x (speed) .

That formula solves all 8 of these problems.
Or rather, it's not the formula that solves them. 
YOU solve them, by using the formula.

#1).                                       Momentum              = (mass) x (speed)

                                               16 kg-m/s              =  (8 kg) x (speed)

Divide each side by (8 kg),
and you have                        (16 kg-m/s) / (8 kg) = Speed

                                                             2 m/s      = Speed

Use exactly the same formula for all the other 7 problems.
