A projectile is fired with initial speed V_0 = 30.0 m/s from level ground at a target that is on the ground, at distance R = 20.0 m, as shown in Fig. 4-51. What are the (a) least and (b) greatest launch angles that will allow the projectile to hit the target?
6. A projectile is fired from ground level, and 10 seconds later hits a target 374 m away and 45 m above the ground. What were the initial velocity and launch angle? 7. The horizontal velocity of a projectile is assumed constant, vx vo cos Bo. The vertical velocity of the ball can be written as a function of time, vy(t)- vo sin 8o + ayt, where the acceleration ay in the y-direction is assumed constant. a. Set the origin...

A projectile is fired from the ground level with an initial velocity that has a vertical component of 20 m/s and a horizontal component of 30 m/s. Find the range R. In the figure below, a constant external force P=160 N is applied to a 20.0 kg box, which is on a rough horizontal surface. While the force pushes the box a distance of 8.00 m, the speed changes from 0.500 m/s to 2.60 m/s. Find the work done by...
If a projectile is fired with an initial velocity of vo meters per second at an angle a above the horizontal and air resistance is assumed to be negligible, then its position after t seconds is given by the parametric equations x = (vo cos(a)t y = (vo sin(a)t - +- 1012 where g is the acceleration due to gravity (9.8 m/s2). (Round your answers to the nearest whole number.) (a) If a gun is fired with a = 30°...
3.00 s after being projected from ground level, a projectile is displaced 27.0 m horizontally, and 45.0 m vertically above its launch point. a) what was the initial horizontal component of the velocity? b) What was the initial vertical component of the velocity? c) what was the initial velocity of the projectile in polar notation?
6. A projectile is fired from ground level at a speed of 25.0m at an angle of 45° above the horizontal. A very big wall is located at a distance of 40.0 m from the firing point. a) How long does it take the projectile to strike the wall? 25.0 m/s 45° 40.0 m b) At what height does the projectile strike the wall? c) When it struck the wall, was the projectile still going up or was it on...
Problem 4: A projectile is fired with an initial velocity of 54.1 m/s, at an initial inclination of 33.7 degrees with the horizontal r-axis. All initial variables (displacement and time) start at 0. You are asked to consider two cases of motion for the projectile, one without drag, and one with drag, with both the cases including effects of gravity. a) For motion with no drag, acceleration vector is given as а -g, where g 9.8 m/s. b) For motion...
