Answer: 7.3 kJ

Explanation:

Work = gravitational potential energy

Amount of work done to lift the box off the ground is stored in the form gravitational potential energy.

W = m g h

where m is the mass = 62 kg

g is the acceleration due to gravity = 9.81 m/s²

h is the height = 12 m

W = 62 kg × 9.81 m/s² × 12 m = 7298. 6 J = 7.3 kJ

Answer:

Power required will be 7.2 watt

Explanation:

We have given battery of Barble jeep is 6 volt

So potential difference V = 6 volt

Resistance of electric motor R = 5 ohm '

We have to find the power motor using to drive the jeep

Power is given by $P=\frac{V^2}{R}$ , here V is voltage and R is resistance

So $P=\frac{V^2}{R}=\frac{6^2}{5}=7.2watt$
