Question

Early one October, you go to a pumpkin patch to select your Halloween pumpkin. You lift the 3.4kg pumpkin to a height of 1.4m , then carry it 50.0 m (on level ground) to the check-out stand. Part A Calculate the work you do on the pumpkin as you lift it from the ground. Express your answer using two significant figures.

Answer 1

Work equals force times distance. In this case, work equals mgh (mg is the force and h is the distance. Solving the equation W = mgh gives you W = (3.4 kg)(9.8 m/s^2)(1.4 m) = 47 J (joules).
