Baseball 0.14 kg moving at 35 m/s. Momentum of the ball?

this should be easy b/c i know p=m*v but i get 4.9 kgm/s and it's wrong.....

I got 4.9 also.

To calculate the momentum of an object, you can use the equation:

Momentum (p) = mass (m) * velocity (v)

In this case, the mass of the baseball is given as 0.14 kg and the velocity is given as 35 m/s. So, let's substitute these values into the equation:

p = 0.14 kg * 35 m/s

Now, simply multiply the numbers:

p = 4.9 kg·m/s

Your answer of 4.9 kg·m/s is correct. It seems that the answer key or the source you're referring to might have made an error. Please double-check the answer key or consult a reliable source to confirm the correct answer.
