An archer shoots an arrow vertically upwards with a velocity of 40 m/s. What will be the maximum height attained by an arrow? Take $g=10m/s^2$.

Q. An archer shoots an arrow vertically upwards with a velocity v. which one of the following graph represent the correct velocity-time graph?

Q. An arrow fired from a bow vertically upwards, attains a maximum height of $5m$ from the ground. If the mass of the arrow is $500g$, calculate the work done by the bow on the arrow (Take g = $10m{s}^{-1}$).

Q. At $t=0$, an arrow is fired vertically upwards with a speed of $100{\text{ms}}^{-1}$. A second arrow is fired vertically upwards with the same speed at $t=5\text{s}$. Then (take $g=10m{s}^{-2}$)(Neglect air friction)

Q. A particle is thrown vertically upwards. If its velocity at half of the maximum height is $10\frac{m}{s}$, then maximum height attained by it is (Take $g=10\frac{m}{s^2}$)
