Question

Our goal in the project Motion Lab be to measure the range R and height h of an object in free fall motion as a function of launch angle and velocity to compare this value and to determine or net our is the x and y can be When the only force on an is the force we say the object is in free fall. Any object in free horizonal (x) be chapter 1.3 your text on Motion Assume the a_x - 0 write out at motion for tree in the horizonal (x) (Use the following as at the initial velocity and t as the time.) Assume the a_y - 0 write out at motion for tree in the horizonal (y) (Use the following as at the initial velocity and t as the time.) h = The initial velocity of a ball launched into free ball is: v_y - 14.85 m/s and theta_i = 25 degree. (a) Calculate the x and y components of the initial velocity. v_a0 = m/s v_mu 0 m/s (b) Calculate the total time of light t_sin of the ball. f_local = 8 (c) Calculate the maximum height b_max of the ball. h_max = m

Explanation / Answer

Apply kinematic equation

vf = vi – g * t, vf = 0, vi = v * sin
0 = v * sin – g * t
t = v * sin / g

Total time = 2 * v * sin / g

v * cos * 2 * v * sin ÷ g = v^2/g * 2 * cos * sin
2 * sin * cos = sin 2
R = v^2/g * sin 2

(4)

h = vyo * t – ½ * g * t^2

(5)

a)

vx= v cos theta = 14.85 cos25 = 13.45 m/s

vy = v sin theta = 14.85 sin 25 = 6.27 m/s

(b)

T = 2 (14.85) sin 25/9.8 = 1.28 s

(c)

h max = ( 14.85)^2 sin ^2 25/ 2(9.8) = 2.0 m
