A coin is pushed from the edge of a laboratory bench with a horizontal velocity of 15.0 ms-1. If the height of the bench from the floor is 1.5m, calculate the distance from the foot of the bench to the point of impact with the floor [g = 10ms-2]
  • A.
    0.75m
  • B.
    2.25m
  • C.
    8.22m
  • D.
    15.00m
Correct Answer: Option C
Explanation

S = U(sqrt{frac{2h}{g}})
= 15(sqrt{frac{2 times 1.5}{10}})
= 8.22m
