Question

A empty truck whose mass is

Answer 1

Answer:

$0.67 m/s^2$

Explanation:

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

$F=ma$

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

$a=1 m/s^2$

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

$F=ma=(2000)(1)=2000 N$

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:

$a=\frac{F}{m}=\frac{2000 N}{3000 kg}=0.67 m/s^2$
