A projectile is fired on level ground with elevation angle α radians, where 0 < α < π/2, and initial speed v0 metres per second. How many metres way does the projectile land if the only force acting on it is gravity, namely −gj metres per second per second, where g is the (positive) gravitational constant. Given an answer in terms of α, v0, and g.

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.

A cannonball is fired horizontally from the top of a cliff. The cannon is at height H = 70.0m above ground level, and the ball is fired with initial horizontal speed v0. Assume acceleration due to gravity to be g = 9.80m/s2 . Part A Assume that the cannon is fired at time t=0 and that the cannonball hits the ground at time tg. What is the y position of the cannonball at the time tg/2? Answer is 52.5 Part...

A projectile is fired from the ground (you can assume the initial height is the same as the ground) in a field so there are no obstacles in its way. It is fired at an angle of 24° with respect to the horizontal and with an initial speed of 25 m/s. Air resistance is negligible in this situation. Call up the positive y-direction, and toward the wall the positive x-direction. What is the earliest time when the height of the...
