seraphim [82]

Answer:

Net force = - 1500 N

Explanation:

We calculate the net force acting using Newton's second Law:

F_{net}=m*a\\F_{net}=(300 \,kg)*(-5\,m/s^2)\\F_{net}=-1500\,N

If a dog has a potential energy of 1500 J and a mass of 24 kg, how high off the ground is he?
Llana [10]

Answer:

h = 6.371 m

Explanation:

Data:

Potential Energy = P.E = 1500 J

Mass = m = 24 Kg

Gravity = g = 9.81 m/sec²

Height = h = ?

Solution:

As the formula for the Potential Energy is;

P.E = mgh

Replacing the values in the above equation

1500 = 24 × 9.81 × h

h = (1500)÷(24 × 9.81)

h = 6.371 m
