Question

# A vessel at rest explodes breaking it into three pieces. Two pieces having equal mass fly off perpendicular to one another with the same speed of 30m/s. The third piece has three times the mass of each other piece. What is the magnitude and direction of its velocity( magnitude in m/s) immediately after the explosion:

Solution

## The correct option is A 10√2,135∘Let v be the velocity of 3rd piece according to figure 3mvcosθ=mu and 3mvsinθ=mu⇒tanθ=1⇒θ=45∘∴3mv=√2mu⇒v=30√23=10√2As seen from the figure, the third piece is inclined at 135∘ w.r. t direction of each one.
