A2-kg bowling ball is 1 meter off the ground on a post when it falls. just before it reaches the ground, it is traveling 4.4 m/s. assuming the there i no air resistace, which statement is true

Well... Since 2+1=3 and 3+1=4 that means 3+4=7. Following me here? Good. Let's move on. Now, we take the 7 and multiply it by 4.4 to get 30.8. Now take your 30.8 and divide it by 360 (degrees; that is the circumference of a circle and the Earth is a circle) to get .08555 repeating. Now add them all up, it should look something like this... 2kg+1m+4.4m/s+.08555= ~8.25kgmm/s. Congratulations! You found the answer! It is about 8.25 kgmm/s squared. Good job!
