Question

A particle of mass 5 units is moving with a uniform speed of v = 32 units in the XOY plane along the line y = x + 4. Find the magnitude of angular momentum

Sum

Solution

Given,

Mass = 5 units

Speed = v = 32 units

Y = X + 4

Angular momentum = L = m(r¯×v¯)

= m(Xi^+yj^)×(vi^+vj^)=m[xvk^-vyk^]=m[xvk^-v(x+4)k^]

L = -mvk^=-4×5×32k^=-602k^

L = 602 units.
