V^2 = Vo^2 + 2g*d V^2 = 0 + 64*(5000-1000) = 256,000 V = 506 Ft/s
a. V^2 = 0 + 19.8*6.4 = 126.72 V = 11.26 m/s.
W1/W2=(F/2 *4d)/(F*d)=(2F*d)/(F*d)=2. W1 = Joe's work. W2 = Mary's work. Joe does twice as much work as Mary.
V = Vo + g*t = 0 t = (V-Vo)/g = (0-2.6)/-9.8 = 0.265 s.
producea java program which when given 3 sides of a triangle determines whether the traingle is an equilateral an issosceles or a scaline
mg*h = 0.5m*V^2 Divide both sides by m: g*h = 0.5V^2 V^2 = 2gh V = sqrt(2g*h.
a = (V-Vo)/t = (10-0)/2 = 5 m/s^2.
Speed = 30m/2s = 15 m/s.
See previous post.
Fn = m*a = 40-24 = Net force. 8a = 16 a = 2 m/s^2.
