Kinetic Energy = 1/2mv^2
m= 1200kg
v= 24 m/s
KE = 1/2 (1200kg)(24m/s)^2 = 345,600 N
Answer:
8.4 V
Explanation:
induced emf, e1 = 5.8 V
Magnetic field, B1 = 0.38 T
magnetic field, B2 = 0.55 T
induced emf, e2 = ?
As we know that the induced emf is directly proportional to the magnetic field strength.
When the other parameters remains constant then
![\frac{e_{1}}{e_{2}}=\frac{B_{1}}{B_{2}}](https://tex.z-dn.net/?f=%5Cfrac%7Be_%7B1%7D%7D%7Be_%7B2%7D%7D%3D%5Cfrac%7BB_%7B1%7D%7D%7BB_%7B2%7D%7D)
![\frac{5.8}{e_{2}}=\frac{0.38}{0.55}](https://tex.z-dn.net/?f=%5Cfrac%7B5.8%7D%7Be_%7B2%7D%7D%3D%5Cfrac%7B0.38%7D%7B0.55%7D)
e2 = 8.4 V
Thus, the induced emf is 8.4 V.
