A19.0-kg cannonball is fired from a cannon with muzzle speed of 1 200 m/s at an angle of 35.0° with the horizontal. a second ball is fired with the same initial speed at an angle of 90.0°. let y = 0 at the cannon. (a) use the isolated system model to find the maximum height reached by each ball. hfirst ball = incorrect: your answer is incorrect. do not try to use equations involving projectile motion. this problem is much more straightforward to solve using energy conservation. m hsecond ball =what is the expression for the total mechanical energy just after the cannon has been fired? what is the expression for the total mechanical energy when the cannonball reaches its maximum height? m (b) use the isolated system model to find the total mechanical energy of the ball❝earth system at the maximum height for each ball. efirst ball = incorrect: your answer is incorrect. how does the total mechanical energy at the maximum height compare to the total mechanical energy immediately after the cannon was fired? j esecond ball =

When a vertical beam of light passes through a transparent medium, the rate at which its intensity i decreases is proportional to i(t), where t represents the thickness of the medium (in feet). in clear seawater, the intensity 3 feet below the surface is 25% of the initial intensity i0 of the incident beam. what is the intensity of the beam "10" feet below the surface? (give your answer in terms of i0. round any constants or coefficients to five decimal places.)
