Accelerations of the car:

  • Let the initial velocity of the car be u.

  • Let the acceleration of the car be a.

  • Using the formula v = u + at, where v is the final velocity and t is the time taken, we can determine the acceleration of the car.

  • From pole A to pole B, the car takes 8 seconds to cover a distance of 50 meters. Therefore, its velocity at pole B is:


vB = u + at1

50 = 0 + a(8)

a = 6.25 m/s2


  • From pole B to pole C, the car takes 7 seconds to cover a distance of 50 meters. Therefore, its velocity at pole C is:


vC = vB + at2

vC = 50 + 6.25(7)

vC = 93.75 m/s


Velocity of the car at A, B and C:

  • The velocity of the car at pole A is 0 m/s since it starts from rest.

  • The velocity of the car at pole B is:


vB = u + at1

vB = 0 + 6.25(8)

vB = 50 m/s


  • The velocity of the car at pole C is:


vC = vB + at2

vC = 50 + 6.25(7)

vC = 93.75 m/s


Distance of pole A from the starting point of the car:

  • The car starts from rest, so its initial velocity u is 0 m/s.

  • Using the formula s = ut + 0.5at2, where s is the distance, t is the time taken, u is the initial velocity, and a is the acceleration, we can determine the distance of pole A from the starting point of the car.

  • From pole A to pole B, the car takes 8 seconds to cover a distance of 50 meters. Therefore, the distance of pole A from the starting point of the car is:
