Q. 40 B4.3( 12 Votes )

# An unloaded truck weighing 2000 kg has a maximum acceleration of 0.5 m/s2. What is the maximum acceleration when it is carrying a load of 2000 kg?

Mass, m = 2000 kg

a = 0.5 m/s2

Now, using F = ma

F = 2000 x 0.5

= 1000 N

m = 2000 + 2000 = 4000 kg

F = 1000 N (remains unchanged)

Again,

F = ma

a = F/m

= 1000/4000

= 0.25 m/s2
