Question

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

Answer 1

607.5 m/s

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

Answer 2

1215

Explanation:

K(E) = MV^2
