Answer:

9567.333

Explanation:

Taking gravity into consideration, we can calculate all this by a formula:

f1 = m*g = 1400*9.81 = 13734 N.

Just like this we can calculate the centrifugal force using the similar formula:

f2 = m*(v∧2)/r = 1400*(25∧2)/210 = 4166.67 N

Therfore the final answer can be calculated as:

f1-f2 = 13734 - 4166.67 = 9567.333

Goodluck, i hope this helps.

The kinetic energy of a nosy is the energy exhibited by the body due to its motion, the kinetic energy of the car is 437500kgm/s

The kinetic energy of a nosy can be calculated using the relation :

  • Kinetic energy = 0.5(mv²)

  • The velocity of the car = 25 m/s

  • Mass of the car = 1400 kg

The kinetic energy of the car = 0.5(1400 × 25²)

Kinetic energy = 0.5 × 1400 × 675

Kinetic energy = 437500 kgm/s

Therefore, the kinetic energy of the car is 437500 kgm/s
