One of my friends in another country has Ti-87 calculator. She can find the button for ln but not for log (to base 10). For now I have told her to calculate logX by lnX/ln10 but is there any single button to calculate log to base 10 directly? Let me know where that button is or if there is any...

1) v^2 = vo^2 - 2gh vo^2 = v^2 + 2gh vo = sqrt(v^2 + 2gh) = sqrt(6.8^2 + 2 * 9.8 * 32) = 26 m/s Ans: 26 m/s 2) S = 5.7 cm t = 14 ms = 14 * 10^-3 s vo = 0 S = vo t + 1/2 a t^2 5.7 = 0 + 1/2 a (14 * 10^-3)^2 5.7 = 98 * 10^-6 a a = 5.7 / (98 * 10^-6) a = 5.82 * 10^4 cm/s^2 1 cm = 10^-2 m = 10^-2...

Velocity is constant. Therefore net force = 0 Therefore resistive force = forward thrust = 7.30E+5 N Ans: 7.30E+5 N _______________.
