Motion in a Straight Line

A horizontal bridge is built across a river. A student standing on the bridge throws a small ball vertically upwards with a velocity of 4 m s−14\ \mathrm{m\,s^{-1}}. The ball strikes the water surface after 4 s. The height of the bridge above the water surface is (take g=10 m s−2g = 10\ \mathrm{m\,s^{-2}}):

  1. A.56 m
  2. B.60 m
  3. C.64 m✓
  4. D.68 m

You have the answer. The worked solution — and why the other three were written — is part of a paid pack.
