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.
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).
