- Check my work Required information A ball is thrown from a point 1.00 m above the ground. The initial velocity is 20.8 m/s at an angle of 30.0° above the horizontal. Find the maximum height of the ball above the ground. m es Next < Prev 19 20 of 208. You fire a ball with an initial speed of v at an angle o above the surface of an incline, which is itself inclined at an angle 0 above the horizontal. a) Find the distance, measured along the incline, from the launch point to the point when the ball strikes the incline. b) What angle o gives the maximum range, measured along the incline? Ignore air resistance.While you are on lookout duty at your fortress, you spot an enemy ship moving directly towards you with a constant speed of 15 m/s. At the moment when the ship is 1.5 km away, you fire a shell at an angle of 45 degrees above the horizontal, which hits the enemy ship. What was the initial speed of the shell to 2 sig figs?
- Why is et = 4/5 i - 3/5 j and en = 3/5 i + 4/5 j . Finding it hard to visualise, are u able to draw it out and derieve it?A bullet is launched with an initial velocity of 400 m / s and an elevation angle of 35 °. Calculate: a) the time it lasts in the air.b) The maximum height reached by the bulletc) The horizontal range of the bullet.A ball is launched from a 10.0 m building with an initial speed of 15.0 ?/?. If the ball’s speed when it reaches its maximum height is 1/3 its speed when it is at half its maximum height, determine ball’s launch angle and the ball’s angle at impact. This is all the information i was given!
- If the stone had been thrown front the cliff too with the same initial speed and the same angle, but above the horizontal, would it’s impact velocity be different?8. You fire a ball with an initial speed of v at an angle o above the surface of an incline, which is itself inclined at an angle e above the horizontal. a) Find the distance, measured along the incline, from the launch point to the point when the ball strikes the incline. b) What angle o gives the maximum range, measured along the incline? Ignore air resistance.A projectile is fired from 3 meters height above level ground with an initial velocityequals to 20 m/s and at an angle equals to 30 degrees above the horizontal level. Notethat the air resistance is neglected. a) Determine, the horizontal displacement when the projectile hits the ground;
- (p) 6) A projectile is fired from ground level with a speed of 80 m/s at an angle 60° above the horizontal on an airless plane where g = 10.0 m/s2. What is the horizontal component of its velocity after 4.0 s?A particle travels along a curved path between two points A and B as shown. Complete the following statement: The displacement of the particle does not depend on A В (A) the shortest distance between A and B. (B) the direction of A from B. the location of A. (D) the distance traveled from A to B.At a long distance shooting match, a bullet is fired with a muzzle velocity of 3000 feet per second from a rifle held in the horizontal position. When fired the sights of the rifle was dead center of a target. The bullet strikes the target at 4.00 ft below the center of the target. How long (in seconds) did it take for the bullet to reach the target? How far away (in unit of yards) was the target? Neglect any air resistance to the bullet. Make a simple sketch. Make a list of all given values, units, and the variables they represent. write the general form of the equation you are going to use. Insert the known values and solve. For problems with vertical motion State at the start of the problem which direction is positive by using an up or down arrow. Keep the velocity components and time to 2 decimal places
