Question

Obtain expression for Time of flight and Horizontal range of a projectile thrown at an angle with the horizontal, with velocity u.​

Answer 1

Answer:

Obtain an expression for Time of flight of a projectile

Explanation:

Consider a projectile fired with velocity V at an angle θ with horizontal.

From equations of motion we write y=ut+
