Problem 2 You throw a rock with initial speed v₂ = 5 m/s, from height h = 12 m above the ground, as shown in the figure. While keep- ing v; constant, you can choose the throwing angle 0₁. The pos- itive value is going slightly up, 0° is throwing horizontally, and negative value is slightly down- ward. DOOOO ● ● ● • The rock reaches the ground in shortest amount of time when... (a) 0 = 30° (b) = -30° (c) 0 = 0° (d) The time of the flight is the same for all throwing angles. • The rock hits the ground with highest speed when...

QUESTION 6 Problem For a projectile lunched with an initial velocity of vo at an angle of e (between 0 and 90°), a) derive the general expression for maximum height hmax and the horizontal range R. b) For what value of 0 gives the highest maximum height? Solution The components of vo are expressed as follows: Vinitial-x = vocos(e) Vinitial-y = vosin(e) а) 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: 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)ayt? 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,…

A ball is kicked from the ground at point 0 with an initial velocity vo = 20 m/s that makes an angle 0 = 30° with the horizontal. This ball reaches its maximum height at point A and then returns to the ground at point B as shown in the figure. (g = 10m/s²) The time taken by the ball to reach the maximum height at point A (toa) is equal to: A. 0.5s B Is C. 15 s D. 2 s E 25s Vo hmax () F5 F6 FB PrtSc Insert Del F9 F10 F11 F12 & 6 7
