Question

10 kg point mass located at the top of a 1.50 m inclined ramp that is without friction. The ramp makes a 30 degree angle with the horizontal. The bottom half of the ramp is on a table and is 0.66 m above the ground.

When mass is released from rest, it slides down the ramp ( a=4.9 m/s2 ) & off the table, then goes through the air until it hits the ground. (table & ramp don't move) The end of the ramp is at the edge of the table. The mass will go straight from the ramp into the air.

i) What would be the speed of the mass once it reaches the end of the ramp?

ii) What is the velocity of the mass at the end of the ramp in terms of ^i and ^j components where ^ i is horiz. & ^ j is vert. need to show which directions are positive.
