A cannon shoots a cannonball from the ground level (ignore the height of the cannon) towards a cliff of height h = 170 m
A cannon shoots a cannonball from the ground level (ignore the height of the cannon) towards a cliff of height h = 170 m. The cannonball is launched with an initial velocity of 110 m/s at an angle of 64° above the horizontal. Neglect air resistance. Assume the cannonball hits the cliff as it descends (on its way down) exactly at the edge, as shown. a. Determine the maximum height above the ground reached by the cannonball.b. What speed will the...

A ball is lunched at to = 0 with a vertical ascending velocity V_0 of magnitude V_0 = 10m/s from point O and at the instant to = 0. The ball describes rectilinear motion on a vertical axis O_z oriented upwards. we neglect air resistance Given g = 10 m/s Study the motion Determine the parametric eq. of motion. Determine with respect to the position of the top S of the trajectory.
