The velocity v→ of a particle moving in the xy plane is given by , with v→ in meters per second and t (> 0) in seconds. at t = 1.6 s and in unit-vector notation, what are (a) the x component and (b) the y component of the acceleration? (c) when (if ever) is the acceleration zero? (d) at what positive time does the speed equal 10 m/s?

electrical potential energy =0.072 j

explanation:

electrical potential energy is given by

u= q δv

q= charge=6 c

δv= potential difference and is given by

δv= e d

e= electric field

d= distance=5 mm=0.005 m

δv=2.4 (0.005)=0.012 v

now electric potential energy= u= q δv

u=6 (0.012)

u=0.072 j
