For a projectile lunched with an initial velocity of v0 at an angle of θ (between 0 and 90o) , a) derive the general expression for maximum height hmax and the horizontal range R. b) For what value of θ gives the highest maximum height? Solution The components of v0 are expressed as follows: vinitial-x = v0cos(θ) vinitial-y = v0sin(θ) a) Let us first find the time it takes for the projectile to reach the maximum height. Using: vfinal-y = vinitial-y + ayt since the y-axis velocity of the projectile at the maximum height is vfinal-y = Then, = vinitial-y + ayt Substituting the expression of vinitial-y and ay = -g, results to the following: = - t Thus, the time to reach the maximum height is tmax-height = / We will use this time to the equation yfinal - yinitial = vinitial-yt + (1/2)ayt2 if we use the time taken to reach the maximum height, therefore, the displacement will yield the maximum height, so hmax = vinitial-yt + (1/2)ayt2 substituting, the vinitial-y expression above, results to…
A rock is thrown out from the top of a 10 m tall building. The initial velocity and angle of the rock are 3 ?/? and 20° below horizontal.(a) What are the horzontal and vertical components of the rock’s initial velocity?(b) How long does it take the rock to hit the ground? (c) What is the horizontal distance, ?, traveled by the rock?
A firework is projected from the level ground in such a way that v0y = 10m/s and v0x = 20 m/s.a) Find the time it takes the firework to reach its maximum height reached.b) Since the firework returns to the ground, it has the same initial and final height. Whenthis happens, the time it takes the object to land is twice the time it takes to reach its maximum height. Using this information, find the horizontal and vertical components of the velocity of the firework right as it lands.
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
