A student fires several projectiles from a 45 degree angle of elevation.  1) at the given angle of elevation what would the range be for a projectile with a speed of 30 m/s 2) at the given angle of elevation what would the range be for a projectile with a speed of 40 m/s 3) at the given angle of elevation what would the range be for a projectile with a speed of 50 m/s

A projectile 10.0 m above ground is fired horizontally with an initial speed of 12.0 m/s the projectile in air = 1.43s the projectile travel before hitting the ground = 17.2 m The fired cannon at several different initial speeds and its corresponding ranges initial speed range 13.0 18.6 14.0 20.0 15.0 21.5 16.0 22.9 17.0 24.3 a. Does range increase linearly with the initial speed? Explain. b. Find the time of flight t and the correlation coefficient r : c. Find the value of g

A projectile is launched with an initial speed of 785 m/s  additionally V(iy) =736 m/s and V(ix) =-273 impact occurs at the same altitude it was launched at determine the following values take up to be positive
