[SOLVED] Kinetic Energy Question
A 7.0 kg bowling ball moves at 2.35 m/s. How fast must a 2.40 g Ping-Pong ball move so that the two balls have the same kinetic energy?
m1= 7.0kg
v1= 2.35m/s
m2= .0024kg
v2=?
I know that:
KE= 1/2mv^2
I set my equation like so:
KE1=KE2
and I reduced it to this:
m1v1=m2v2
I plugged in the values and solved for v2:
(7.0kg)(2.35m/s)=v2 (.0024kg)
v2= 6854.17
I put this answer in and it tells me...
wrong check mark
Your answer differs from the correct answer by orders of magnitude. m/s
What am I doing wrong? Please point me in the right direction.
