1) Solve the following: A dog weighing 15 kg is running at 9 m/s. What is the kinetic

energy?

607.5 m/s

Step-by-step explanation:

K. E. = 1/2 m v^2

mass = kg

m = 15

velocity = m/s

v = 9

now substitute the variables

1/2 (15) (9) ^2

first square the 9

(9) ^2 = 9 times 9 = 81

1/2 (15) (81)

now multiply 15 and 81

15 times 81 = 1215

1/2 (1215)

now divided 1215 by 2

1215/2 = 607.5 m/s

1215

Step-by-step explanation:

K (E) = MV^2
