A projectile is fired from the surface of the Earth with a speed of 200 m/s at an angle of 45° above the horizontal. If the ground is level
a. what is the maximum height reached by the projectile?
b. What is the range of the projectile?
c. What is the total time in flight?

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?
