Hi I really need a answer to this task. Hope anyone can help.
A curling stone ( named A ) gets on the ice with a unknown beginning velocity Vo
the stone moves along a straight line ( x-axis ) on the x-axis further ahead lies another
stone ( named B ) still. Stone A collides with stone B in a sloped hit/knock
Just before the hit stone A has a velocity of 2m/s. After the slope stone A moves
straight with a angle of 45 degree in proportion at/of the x axis. Equivalently for stone B is -30 degrees.
a ) Estimate the velocity of each stone have just after the collision
b) Estimate the loss of kinetic energy in this collision. A curling stone have mass 20kg. what kind of collision is this ?
The reason for the energy loss is that big is that ice-sludge came between the stones in the collision. We clean up and retake the attempt. Now we reckon that the push is approximate perfect elastic Stone A has the velocity of 2 m/s before the push/hit and 1,5m/s after. The direction of a form the angle 41,3 degree with the x-axis after the push/hit.
c) Find the velocity and direction of B after the stone is Pushed/released.
d ) Check that the push of the stone is approximated elastic, by calculate the x component
