First slide

The two types of acceleration

Question

A truck is carrying a box of mass m = 50 kg on its flat horizontal rough surface with coefficient of friction $μ =$ 0.3. It is crossing a circular track of radius 27 m. What is the maximum speed of the truck so that the box does not slide from the truck while moving on the circular path?

Moderate

A

18 km/hr
B

36 km/hr
C

32.4 km/hr
D

None of these

Solution

F.B.D. of the particle in truck travel.
Here $\frac{{mv}^{2}}{R} = μmg$
$v^{2} = μ g R = 0.3 \times 10 \times 27 m / s = 32.4 k m / s$
