- Homework Statement
- A ball of mass 𝑚=4.07kg is thrown over level ground in a region where the electric field is 𝐸⃗=5.5N/C𝑖̂. The ball has a charge 𝑞=1.59C. The ball was thrown from the origin with an initial velocity of 𝑣⃗𝑖=5.58m/s𝑖̂+16.55m/s𝑘̂. Gravity provides an acceleration of 𝑔⃗=−9.8m/s^2𝑘̂. What is the x-component of the position vector where the ball lands?

- Relevant Equations
- t = 3.377s

x = 18.84m which is wrong

I first calculated the time using y = (viy)(t) + 0.5gt^2 where y is the vertical displacement which is 0 for the ball landing back on the ground, viy is the initial vertical velocity ie 16.55m/s and g = -9.8m/s}^2. I get 2 values for t, t=0 and t= 3.377s. Then using the equation x = (vix)(t) = (5.58m/s)(3.377s) I get x as 18.84m. The correct answer is 31.13m and I am not sure where I am going wrong.

Could someone please help me with this and let me know where am I making an error?

Thank you
