Projectile fired at angle: find maximum height, range, angle and flight time

[markiii]

A projectile is fired with speed v_0 at an angle
Find the highest point in the trajectory,H .
Express the highest point in terms of the magnitude of the acceleration due to gravity g, the initial velocity v_0, and the angle .
What is the range of the projectile,R ?
Express the range in terms of v_0,angle , and g.
Find the angle above the horizontal at which the projectile should be fired.
What is the initial speed?
Find t_g , the flight time of the projectile

 

[Saketh]

Use the kinematic equations to solve for all of the requested values.

 

[gunblaze]

Show some of ur own workings first. Like what Saketh have suggested. use the kinematics eqns to solve ur problem. These qns are quite straightforward.

Decompose the velocity as x and y components first.
the X and Y components are independent to each other
