The shell you find on the beach isn't as pretty as you thought. So you toss it horizontally at 0.6 m/s into the water from a height of 1.3 meters. How far will it travel horizontally before hitting the water?

The shell you find on the beach isn't as pretty as you thought. So you toss it horizontally at 0.6 m/s into the water from a height of 1.3 meters. How far will it travel horizontally before hitting the water?

• You only need the x= equation

• You only need the t= equation

• First use the t= equation, then use the x= equation

• First use the x= equation, then use the t= equation

You spot a lovely 0.004 kg shell on the beach. You pick it up and lift it 1.3 meters. How much work did you do?

Choose TWO thought processes that will solve this problem

• Work = Fd

  F = weight

  weight = mg

• Vertical Work is stored as PE

  Work = PE = mgh

• the shell is a projectile, so use projectile equations.

• Since the shell accelerated up, use F = ma to find the net force, then use Work = Fd
