A projectile is thrown with a speed 20 m/s at an angle 53° with the horizontal. It lands on a platform with minimum speed and continues moving with the same speed. Which of the flowing is/are correct :-

Options:(select one or more)

Answer:

B, D

Solution:

Time taken by projectile to reach the left end of plateform $t = \frac{T}{2} = \frac{u s i n θ}{g} = 1.6 sec$ For $t \leq 1.6 sec$ $x = u_{x} \cdot t = 12 t$ and $y = u_{y} t + \frac{1}{2} a_{y} t^{2} = 16 t - \frac{1}{2} gt^{2}$ $t > 1.6 sec \Rightarrow x = \frac{R}{2} + 16 (t - 1.6), R$ is range
