Find the net force of the two concurrent forces, and then reverse the direction of the net force. There's your equilibriant. SIMPLE ex: 2N east Equilibriant: 2N west
Umm, just add them together and divide by 2... 17.5 + 35 = 52.5... Divided by 2...26.25..
d = m/v d = 5g / 10cm3 d = 0.5 g/cm3
Whats the equation? If point is just 1, then there is an undefined tangent. Since the tangent will be vertical.
Kinematic equation: d = vi*t + (1/2)a*t^2 Since its moving at 3.6m/s in the horizontal direction, disregard it. Hence initial velocity is 0 1.2m = 0 + (1/2)9.81m/s^2 * t^2 (1.2m / (1/2)9.81 m/s^2) = t^2 (1.2m / (1/2)9.81 m/s^2)^1/2 = t t = 0.49 s
Assuming acceleration is the force of gravity. Vf = Vi + a*t Vf = 18m/s + 9.81ms^-2 * 15s Vf = 165.15 m/s d = Vi*t + 1/2a*t^2 358 = 18m's*t + (1/2)9.81ms^-2 * t^2 Set it to zero: 0 = 4.91ms^-2 * t^2 + 18m/s * t - 358. Use quadratic formula t = 6.9s or t = -10.5s Can't ...
F = kx ma = kx 480kg * (4*9.81) = k * 11.8m k = 1596.20339
EDIT: Change 250x = 5000 - 2500 to: 250x = 5000 - 2800
Let x = part - time staff Total cost for full-time workers = 350 * 8 = 2800 2800 + 250x = 5000 250x = 5000 - 2500 x = 8.8 Since I have not met 4/5'ths of a person we would have to either round up or down. Since the daily wage cannot exceed $5000 we will round down to 8. Th...
