Look at the picture to the right. The truck
is out of gas. The truck has a mass of 1500 kg and
is loaded with 1000 kg of furniture. The man must
apply 82 N of force for 60 seconds to bring the
truck from rest to a velocity of 2.0 m/s. If the man
had first unloaded half of the furniture (500 kg),
only 66 N of force for 60 seconds would be needed
to reach the same velocity. If he had unloaded all
of the furniture, only 50 N of force for 60 seconds
would be needed to reach the same velocity.
Calculate the acceleration of the loaded truck, half-loaded truck, and empty truck.

Answers

Answer 1

Loaded Truck: The acceleration of the loaded truck can be calculated using the equation: a = (F/m) = (82N/2500kg) = 0.032 m/s².

What is acceleration?

Acceleration is a change in the speed or direction of an object’s motion. It is measured in meters per second squared (m/s2) and is caused by an unbalanced force acting on the object.

This means that the loaded truck requires 82 N of force to accelerate at 0.032 m/s² for 60 seconds in order to reach the velocity of 2 m/s.
Half-Loaded Truck:
The acceleration of the half-loaded truck can be calculated using the equation: a = (F/m) = (66N/2000kg) = 0.033 m/s². This means that the half-loaded truck requires 66 N of force to accelerate at 0.033 m/s² for 60 seconds in order to reach the velocity of 2 m/s.
Empty Truck:
The acceleration of the empty truck can be calculated using the equation: a = (F/m) = (50N/1500kg) = 0.033 m/s². This means that the empty truck requires 50 N of force to accelerate at 0.033 m/s² for 60 seconds in order to reach the velocity of 2 m/s.
