Two canoes are touching and at rest on a lake. the occupants push away from each other in opposite directions, giving canoe 1 a speed of 0.56 m/s and canoe 2 a speed of 0.45 m/s .

if the mass of canoe 1 is 320 kg , what is the mass of canoe 2?

398.22 kg

Explanation:

= Mass of canoe 1 = 320 kg

= Mass of canoe 2

= Velocity of canoe 1 = 0.56 m/s

= Velocity of canoe 2 = 0.45 m/s

In this system the linear momentum is conserved

The mass of the second canoe is 398.22 kg

probably not if net force is zero

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
