Sample Questions

Q1.Two cars move in the same direction with speeds 60 km/h and 80 km/h. The velocity of the faster car relative to the slower car is:

  • A20 km/h
  • B140 km/h
  • C70 km/h
  • D80 km/h

Q2.A ball dropped from 90 m height loses one-tenth of its speed at each bounce. After the first bounce, it rises to approximately:

  • A72.9 m
  • B81.0 m
  • C73.0 m
  • D90.0 m

Q3.A woman walks at 5 km/h for 30 min to her office 2.5 km away, and returns by auto at 25 km/h. The average velocity for the round trip (0 to 50 min) is:

  • A5 km/h
  • B6 km/h
  • C0 km/h
