You just found out that the balance in one of the company's bank accounts dropped below $0 to –$425.59. now you must adjust the balance to include the $30 penalty that the bank will charge, and then transfer funds from another of the company's accounts. what is the balance after the penalty and before you transfer any funds? –$395.59

The correct answer is -$455.59.

The balance in the account after it is overdrawn is -$425.59, and the the bank charges them an additional $30 fee, which will be subtracted from the account.

-$425.59 - $30 = -$455.59

ek = (m·v2) / 2

v - velocity of system after the collision

m = m1 + m2

ek = (m1 + m2) ·v2/2

ek = (200 + 250) ·2,32/2 = 450·5,29/2 = 1190,25 j
