निम्न में से कौनसा ग्राफ किसी प्रक्षेपण की ऊँचाई $(h)$ तथा इसमें लगे समय $(t)$ के बीच के संबंध को व्यक्त करता है, जब प्रक्षेप्य को जमीन से प्रक्षेपित किया जाता हॅै

A
B
C
D

Solution

(c) Height of the projectile $h=u t-\frac{1}{2} g t^{2}$

which is a parabola. When a projectile is projected at some angle from the horizontal, the projectile attains a maximum height after some time and after that it starts to fall down and finally comes to the ground. So correct graph is option $\mathrm{C}$.
