Aempty truck whose mass is
2000kg has a maximum acceleration of
im/s. what will its maximum
accelerate when it carries a load of 1000kg

Explanation:

We can solve the problem by using Newton's second law:

where

F is the net force on the truck

m is the mass of the truck+load

a is the acceration

At the beginning, the mass of the truck is

m = 2000 kg

and its acceleration is

So, the maximum force that the engine of the truck can produce is

Later, a load of 1000 kg is put on the truck, so the new mass is

m = 2000 + 1000 = 3000 kg

The maximum force that the engine can produce is the same, so the new maximum acceleration of the truck will be:

potential energy is directly proportional to height.

more height = more potential energy.

greatest increase in height = greatest increase in potential energy

where are the points with the greatest increase in height ?

has to be c-e or d-e .
