A projectile is fired at speed v0 and angle
. What is the
radius of curvature of the parabolic motion (a) at the top? (b) at
the beginning? (c) At what angle should the projectile be fired so
that the radius of curvature at the top equals half the maximum
height?
Homework Answers
It must be near to 45 degree because it gives the maximum range.....For more details google out the projectile range and height of projectile motion formulae......Thanx

A projectile is fired with an initial speed of 20. m/s at an angle of 42.2° above the horizontal on a long flat firing range. Determine, a) the maximum height reached by the projectile, b) the total time in the air, c) the total horizontal distance covered (that is, the range), d) the speed of the projectile 1.50 s after firing. e) direction of the speed at 1.50 s.
A projectile is fired with initial velocity v0 = 95 m/s at an angle θ = 50°.
Problem 8:A projectile is fired with initial velocity v0 = 95 m/s at an angle θ = 50°. After 5 s it strikes the top of a hill. What is the elevation of the hill above the point of firing? At what horizontal distance from the gun does the projectile land?

A projectile P of mass m is fired from a point 0 with initial speed v0 at launch angle φ0 above a horizontal firing range. In addition to gravity, P is subject to the aerodynamic drag force by the surrounding air modeled as a quadratic function of speed where v is the velocity of P and k is a positive pa- rameter. 0 0 We are interested in studying the effect of Faero on various aspects of projectile motion. Since...
