Suppose that you are viewing a soccer game from a helicopter above the playing field. two soccer players simultaneously kick a stationary soccer ball on the flat field; the soccer ball has mass 0.420 kg. the first player kicks with force 162 n at 9.0° north of west. at the same instant, the second player kicks with force 215 n at 15° east of south. find the acceleration of the ball in i ^ and j ^ form.

f=ma newton's second law 7x8=56n

c) up is the direction the magnetic force is acting on the charge.

find the surface area of the sphere to the nearest square unit. use a calculator.

a. 254 in.2

b. 64 in.2

c. 127 in.2

d. 1,018 in.2

energy stored in the capacitor= 9.72 x 10⁻⁴ j

explanation:

the energy stored in the capacitor is given by

e= 1/2 c v²

e= energy stored

c= capacitance= 1.5 µc= 1.5 x 10⁻⁶f

v= potential difference=36 v

so energy stored= e= 1/2 (1.5 x 10⁻⁶) (36)²

energy stored= 9.72 x 10⁻⁴j
