how to find flight time/distance and greatest hight of projectiles?

a is acceleration, v is velocity, s is position vertically: a = - g v = u - gt (by integrating with respect to t and setting initial speed u as constant of integration) s = ut -gt 2 /2 + s 0 (by integrating ...

Sketch the graph y=Ax^2 where A is a constant

If A is negative, then it would be like an upsidedown 'bucket' where the only intersection is in the origin. If A is positive, then it would be similar but flipped on the x-axis. So it would look like a 'buc...
