Question

The acceleration due to gravity on earth is 9.80 m/s2. if the mass of a dog is 40.0 kg, what is the weight of the dog? 4 n 40 n 392 n 490 n

Answer 1

Weight = mass * acceleration

W = 40*9.8

= 392N

Answer 2

Answer: The Weight of the dog is 392 N.

Step-by-step explanation:

Acceleration due to gravity ,(g):
`9.80m/s^2`

Mass of the dog,(m) = 40 Kg

Weight is measure of force exerted by gravity on the object. Its S.I units are Newtons (
`kg* m/s^2`)

Weight= mass × g

`40* 9.80m/s^2=392 N`

Hence, the weight of the dog is 392 N.
