block slides across table with initial speed of 8 m/s coefficient of friction between block and table is .5 and table is 4 m long and 1.2 m high determine how far the block lands from the base of the table

Answer 1

ok, first you are looking for the horizontal velocity at the end of table.

KEfinal=KEinitial-mu*mg*distance
vf^2=vi^2-2*.5)9.8*4
compute vf.

Now, knowing the height of the table, compute iime in air.
1.2=1/2 g t^2 solve for time in air t.
horizontal distance=vf*t
