Thank you.

1. A 45kg sprinter runs at 12 m/s for a short distance. What is his momentum? 2. p=m*v 3. p= (45kg)(12m/s) p= 540 I'm not sure if I did it right. & am I supposed to include unit(s) after 540? :confused:

I did my work on a paper first, then I posted in here. 'Cause I'm not sure if I did it right or not. & I didn't realized we have too post a solution. Sorry bout that.

I just edited my post. So, will this thread be deleted?

I'm kinda confused. :confused:

1. A car accelerates from a standstill to a speed of 30 m/s in a time of 10 seconds. What is its acceleration? 2. Equation for acceleration: a=(vf-vi)/t3. a= ? (it asks for acceleration) vf= 30 m/s vi= 0 m/s t= 10s 30 m/s - 0 m/s / 10s = 3 a= 3 m/s^2 I'm not sure if I did it right.

I know cm^2 is centimeter squared & cm^3 is centimeter cubed, but what does it means?
