Physics · Work, Energy and Power
A particle of mass m is projected with speed u at an angle θ = 60° with the horizontal. At the highest point of its trajectory, it collides completely inelastically with another particle of the same mass m moving horizontally with velocity u. The horizontal distance covered by the combined mass before reaching the ground is:
- 15√3 u28g
- 2√3 u24g
- 32√3 u25g
- 43√3 u28g✓
Correct answer
3√3 u28g
