Question

An unloaded van weighing 1000kg has a maximum acceleration of $1/m{s}^2$. The maximum acceleration when it is carrying a load of 1000 kg is:

• A. $1m/s^2$
• B. $2m/s^2$
• C. $0.5m/s^2$
• D. $10m/s^2$

Answer 1

Answer: (C)

$0.5m/s^2$

Net force acting on the van initially $F=ma=1000\times 1=1000$ N

Now the mass of the loaded van $N=2000$ kg

$\therefore$ Its maximum acceleration $a_{max}=\frac{F}{M}=\frac{1000}{2000}=0.5$ $m/s^2$
