A boy carries a 50 N box up a flight of stairs 10-m high. How much potential energy has the box gained?

almond37 [142]

Answer:

Potential energy, P = 500 J

Explanation:

We have,

Weight of the box, W = 50 N

Height of the stairs, h = 10 m

It is required to find the potential energy gained by the box. The potential energy is possessed by an object due to its height. The formula of potential energy is given by :

$P=mgh$

g is acceleration due to gravity

$P=50\ N\times 10\ m\\\\P=500\ J$

So, the potential energy of 500 J is gained by the box.

An object of mass 1.5 kg rests on a shelf where it has a gravitational potential energy of 7 joules. An object of mass 4.5 kg is

bija089 [108]

Answer:

C. 21 Joules

Explanation:

We apply the formula to calculate the potential energy (Ep):

Ep=m*g*h

Where:

Ep : potential energy in Joules (J)

m :mass in kilograms (kg)

g acceleration due to gravity (m/s²)

h: height in meters (m)

Calculation of the height (h)

Ep = m*g*h

7 = (1.5 )*(9.8) *(h )

7 = (14.7) (h )

h = 7 / (14.7)

h= 0.476 m

Gravitational potential energy of the second object

Ep = m*g*h

Ep = (4.5 )*(9.8) *(0.476 )

Ep = 21 J
