Question

A Tyrannosaurus rex did 107 J of work to lift its dinner, 2721 m from the ground.

What force did the Tyrannosaurus rex raise its dinner?

Answer 1

Answer: 0.04 Newton

Step-by-step explanation:

Work is done when force is applied on an object over a distance. It is measured in joules. Workdone = Force x distance

Since, Work = 107 joules

Force = ? (Let unknown value be Z)

Distance = 2721 metres

Workdone = Force x distance

107J = Z x 2721metres

Z = (107J / 2721 metres)

= 0.039 Newton (approximately 0.04N)

Thus, 0.04 Newton is the force applied by the Tyrannosaurus rex.
