What is the kinetic energy of a 26 kg dog that is running at a speed of 8.4 m/s (about 19 mi/h)?

Ke = .5mv^2 so the ke is .5(26)(8.4^2)= 917.28

Can you calculate
Kinetic Energy = (1/2) M V^2 ?
The answer will be in Joules if you use the right units for M and V. 
A microwave oven has a power requirement of 1235 W. A frozen dinner requires 6.0 min to heat on full power.
(a) How much electrical energy (in kWh) is used?
1 kWh
(b) If the cost of electricity is 12 cents per kWh, how much does it cost to heat the dinner?
