1. A block with the mass m=2,0kg is dropped from 0,5 meters above an incline with an angle of 30 degrees. The incline stands on a table , as shown in the following picture. The table is 2 meters high. The friction is negligible.
a) Determine the acceleration of the block while sliding on the incline
b) Determine the v of the block when leaving the incline
c) How far from the table will it land
d) How long time does it take from the starting position until the block hits the floor.
e) Does the mass of the block play any role at all?
a) m_tot= 2kg
a=F/m
Since only the x composant of the weight (FG) will help the block accelerate
a=2*g*sin 0,3 / 2kg = g/2kg= 4,91 m/s^2
b) The first free fall gives v final from:
Hwwever, then I am stuck on how to continue on b ), i need to find s of the incline, or v final of the incline. Or do i need to put v-final as 0 and solve from it hits the incline until the floor, instead of making one calculation for just the incline?
