THANK YOU FOR ALL YOUR HELP...

A.)27.1 B.)83.2 C.)34.1 D.)68.4


2.) The kinetic energy of a 12 kg mass was increased from 0 Joules to 196 Joules in a time of 3.2 sec. Determine the power delivered to the mass.
A.)26.1 Watts B.)16.3 Watts C.)43.7 watts D.)92.1 watts

Take note that we DO have a homework section here on PF. Also, you should, at the very least, showed what you have attempted to do so that we know what YOU know and can start from there.
