Question

An empty truck whose mass is 2000 kg has a maximum acceleration of 1 m/s2. What will its
maximum acceleration be when it carries a load of 1000 kg?

Answer 1

Answer:

force moving the truck = empty truck mass x max. acceleration

= 2,000 kg x 1 m/s²

= 2,000 N

That force is the maximum force truck can generate, so it will be the same when it has a load of 1,000 kg.

So,

2,000 N = mass with load x acceleration

2,000 N = (2,000 kg + 1,000 kg) * acceleration

2,000 N = 3,000 kg × acceleration

=> acceleration = 2,000 N / 3,000 kg

=> acceleration = 0.67 m/s²

Its maximum acceleration will be 0.67 m/s².
