  2. 2a) vertical velocity = 15m/s, horizontal velocity = 26m/s
  3. 2b) 1.5 seconds to reach the top
  4. 2c) Remember to double the time. Distance = 78m
  5. 3a) 3m/s2
  6. 3b) 30 N
  7. 4a) 147 000 N
  8. 4b) 327 000 N
  9. 5a) 294 N
  10. 5b) frictional force = 294 N
  11. 6a) 3m/s2
  12. 6b) 512 N
  13. 6c) 272 N
  14. 6d) 0 N
