The time taken for the ball to strike the ground is given by (A) -h=vt-\dfrac{1}{2}gt^{2} (B) h=vt-\dfrac{1}{2}gt^{2} (C) \dfrac{1}{2}gt^{2} (D) \sqrt{\dfrac{2g}{h}} Answer : option (A) Solution : Related Previous Post The initial velocity of a body moving along a straight line is 7 ๐/๐ . It has a uniform acceleration of 4 ๐/๐ 2 . The distance covered by the body in the 5 ๐กโ second of its motion is Next Post An express train is moving with a velocity ๐ฃ1. Its driver finds another train is moving on the same track in the same direction with velocity ๐ฃ2. To escape collision, driver applies a retardation ๐ on the train. The minimum time of escaping collision will be
