A body is projected horizontally from a height with speed 20 metres/sec . What will be its speed after 5 seconds ( \(g = 10 \, \mathrm{metres/sec^{2}}\)
Text Solution
Verified by ExpertsThe correct answer is:
A
Horizontal velocity \(v_x = 20 \, m/s\)
Vertical velocity \(v_{y} = u + gt = 0 + 10 \times 5 = 50 m/sec\)
Net velocity \(v = \sqrt{v_x^2 + v_y^2} = \sqrt{(20)^2 + (50)^2}\) = 54 m/s.
