1. ### Solving for v_o_???

20m = (v_o_sin35°)(159m/v_o_) - (4.90 m/s)(159m/v_o_) 20 = 159*sin35° - 4.9*159/v_o_ 4.9*159/v_o_ = 159*sin35° - 20 multiply v_o_ on both sides: 4.9*159 = (159*sin35° - 20)*v_o_ divide 159*sin35° - 20 on both sides: v_o_ = 4.9*159/(159*sin35° - 20)

2. ### Physics: Ek=1/2mv2 solve for v?

E = 1/2 m v^2 divide both sides by 1/2 m 2E/m = v^2 swap sides...and m are both positive, so you can take the square root of both sides: v = √(2E/m) Then plug in your numbers: v = √(2...

4. ### A particle moves in a straight line so at time,t its displacement from the origin is x and its velocity is v.?

1) v = u + at u = 0 at time t so ignore it. v = at t = v / a t = v / (4 - v^2) 2) x = ut + 1/2at^2 (u =0...sqrt(2)t - vt sqrt(x) = (sqrt(2) - v)t sqrt(x) / t = sqrt(2) - v sqrt(2) - (sqrt(x) / t) = v I think.. Just make sure...

6. ### An electric potential is 1500 V and the magnitude of the electric field is 1.0×105 V/m.?

V(=1500)=kQ/r ------- (1) E(=10^5)=kQ/r^2--------(2) (1)÷(2) V/E=r therefore r=1500/10^5=1.5*10^(-2)m=1.5cm the electric potential at distance...
