2.how would the kinetic energy of a 12,000-kg train compare with the kinectic energy of a 900-kg compact car if both were traveling at the same speed?

Question

A.the trains kinectic energy would be equal to the cars kinectic energy.

B.the trains kinectic energy would be greater than the cars kinectic energy.(I pick B.)

C.the trains kinectic energy would be less than the cars kinectic energy.

Answer 1

(1/2) m v^2 is certainly bigger for the train because (1/2) is the same and v^2 is the same but m is MUCH MUCH bigger

so I agree, B

Answer 2

is it b??????
