A spring is on top of a table that is 1.73m above the ground. A spring with a strength constant of 17.5 N/m is compressed 0.05m and used to fire a 0.006kg ball off the table Q: how fast is the ball traveling when it reaches the ground (us formula PEgrav(initial)+PEelastic(initial)+KE(initial)=PEgrav(final)+PEelastic(final)+KE(final)
