Place a 50g load on the hanger and measure the extension. Add 50g load on the hanger in about 5 steps and measure the extension each time. Plot a graph between load and extension . repeat this activity with springs made of iron,copper and brass. Plot load extension graph in each case compare these graphs. Which of the above material obey hooks law?

take a plastic pipe and fix a jet at one of its end.connect the pipe to a water tap attached to a large overhead water tank.fix a large protractor,so that you can hold the pipe at different angles(at 15',30',45',60')
Hold the pipe in such a manner that jet of water comes out of an angle 15' .measure the distance up to which water is reaching.this is the range of the projectile.
Now hold the pipe at an angle 30',45'and 60' .measure the range of the projectile in each case.
keep the speed of water coming out of the jet same in each case.
what do you find?for a given speed,the range is maximum when the angle of projection is 45'.
Also try to find out the effect of initial speed of water on the range of the projectile.

A diesel locomotive of mass 30 tonne is travelling at 1.8 m/s when it couples with a series of coaches of total mass 350 tonne, whilst the coaches are stationary. Ignoring the effect of energy lost in the buffers and couplings, what is the speed immediately after impact of the whole train?

A motorcycle has a velocity of 40 m/s when the brakes are applied to bring it to rest in 3 s. If the road wheels have a radius of 0.45 m determine the number of revolutions made by the wheels in that time.

A cyclist starts from rest down a hill, of gradient 1 in 30. The gearing allows a constant tractive force of 180 N. The resistance to motion is 30 N. The total mass of cycle and cyclist is 85 kg. Calculate the constant acceleration in m/s2

a car accelerates at 2m/s^2. assuming the car starts from rest,how much time does it need to accelerate to a speed of 30m/s?

a block(8.5kg) is fixed in aa frictionless incline plane by a rope. the angle θ= 30. what is thnormal force acting on the block.
Answered!
A car of mass 120 kg is moving at 100 m/s. If it slows down to 40 m/s in 50 seconds:

A. The impulse and force that are being provided by the breaking mechanism is when the mechanism is brought to a stop and then “throw it back.” Impulses are greater when bouncing occurs.

I was actually impressed with all the answers. A few of the questions I'm still confused on how you got to that step of the equation, maybe for the future you can type in a few more steps in how you got the answer you did. This was a lot of help though.
