# A ball with a mass of #600 g# is projected vertically by a spring loaded contraption. The spring in the contraption has a spring constant of #16 (kg)/s^2# and was compressed by #3/5 m# when the ball was released. How high will the ball go?

The height is

The energy stored in the spring will be converted to kinetic energy and this will give the initial speed of the ball.

We apply the equation of motion

To find the greatest height

So,

When evaluating a one-sided limit, you need to be careful when a quantity is approaching zero since its sign is different depending on which way it is approaching zero from. Let us look at some examples.

- If a spring has a constant of #8 (kg)/s^2#, how much work will it take to extend the spring by #40cm #?
- If a #5 kg# object is being constantly accelerated from #0m/s# to #12 m/s# over # 16s#, how much power is being applied at #t= 1 s#?
- How much work would it take to push a # 12 kg # weight up a # 8 m # plane that is at an incline of # pi / 3 #?
- An object with a mass of #200 kg# is hanging from an axle with a radius of #6 cm#. If the wheel attached to the axle has a radius of #32 cm#, how much work would it take to turn the wheel a length equal to the circumference of the axle?
- A balanced lever has two weights on it, the first with mass #7 kg # and the second with mass #30 kg#. If the first weight is # 7 m# from the fulcrum, how far is the second weight from the fulcrum?
