1) A car with an initial velocity of 10.8 km/h experiences an acceleration of - 0.82 m/s2 for 2.0 s.
(a) Calculate the car’s final speed.
(b) What is the car’s displacement?

2)A plane traveling at – 45 m/s slows down to – 15 m/s in a time of 8.0 s.
(a) What was the planes displacement during this
time?
(c) What was the plane’s acceleration during this time?

I need help asap ;-_(

the electric field is a “force field” around a charged object that illustrates the direction the electric force would push an imaginary 

1.195000

explanation:

total mass=0.0117+0.0137+0.0881+0.0111

total mass= 0.01172kg

total velocity = 0.283-0.743+0.871-0.799+0.155+0.637+0.301=0.102

momentum=mv=0.1172*0.102=1.195000//

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
