PLEASE HELP, DUE TOMORROW!!! 1) What is the velocity of the object at the
following times? Be sure to include direction.
(a) t=1.0s
(b) t=40s
(c) t=
6.0 s
2) What is the acceleration during each of the
following time intervals? Be sure to include
direction.
(a) ‡= 0.0 s-t = 2.0 s
(6)+=2.0 s-t=3.0s
(c) t=3.0s-t=5.0s
(d) t= 5.0 s-t= 8.0 s
3) In a short sentence, describe the motion of the
object in each of the following time intervals.
(a) t=0.0s-t=2.0s
(b) € = 2.0 s-t = 3.0 s
(c) t= 3.0s-t= 5.0 s
(d) t= 5.0 s-t= 8.0s

a sonic boom is a loud boom that breaks the sound barrier

explanation:

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
