A. What is the minimum speed needed to make a projectile shot at an angle of 35" above the ground travel through a hoop 10 m above the ground? b. How far away does the hoop need to be from where the projectile starts?

c. If the projectile lands 3 m below where it started, how long will it be in the air? What is its velocity when it hits the ground?

Aspecified volume of space contains an electric field for which the magnitude is given by e=e0cos(ωt). suppose that e0 = 20 v/m and ω = 1.0 × 107 s−1. part a what is the maximum displacement current through a 0.80 m2 cross-sectional area of this volume? express your answer with the appropriate units. idisp,max i d i s p , m a x = nothing nothing request answer part b how would this area have to be oriented relative to the electric field to get this maximum displacement current?
