### HW 1B #27

so the speed is + or - 5 m/s so how do you know to multiply the mass (8.00 kg) by 10 instead of just 5 m/s?

The question is saying the bowling ball is moving at 5+5 m/s (10 m/s) or 5-5 m/s (0 m/s). That's why you multiply the mass by 10 m/s.

I used 5.00 value for delta v

Edit: Do not use 5.00 value for delta V:

Lavelle addressed this in his solution manual so we use 10 as delta v
