Question

An unlouded truck weighing 2000kg has a maximum acceleration of 5m/s2. What is the maximum acceleration when it is carrying a load of 2000kg?​

Answer 1

Given :-

◉ An unloaded truck of mass, m = 2000 kg moves with a maximum acceleration of a = 5 m/s²

To Find :-

◉ Maximum acceleration when it is carrying a load of 2000 Kg

Solution :-

Now the force applied by the truck would be constant in both the cases. So, First, let us find the force applied by the truck while moving unloaded.

We know,

⇒ Force = Mass × Acceleration

⇒ Force = m × a

⇒ Force = 2000 × 5

⇒ Force = 10000 N ...(1)

Now, While moving loaded with a load of 2000 Kg, the mass of the truck-load system would become, m + 2000 ⇒ 4000 Kg

Since the force applied by the truck is 10000N , Let us find the maximum acceleration produced:

⇒ Force = Mass × Acceleration

⇒ 10000 = 4000 × A

⇒ A = 10000/4000

⇒ A = 10/4

∴ Acceleration produced = 2.5 m/s²

Some Information :-

◉ Force = Mass × Acceleration

It also equals to rate of change of momentum.

◉ Momentum of a body = Mass × Velocity

Momentum of a system or body is conserved.

Answer 2

Explanation:

momentum body = mass × x

force= mass +acceleration

thus, momentum or body is conserved
