Hi guys. First of all, great forum you've got here.
I have a problem and I hope you can help me with this one.
Block of mass m lies on a rough horizontal surface. In the period 0 - t1, the block is moving due to the force F(t), which varies depending on the time. In period t1 - t2 we only have friction (F=0), and the block in the time t2 has speed v2=1 m/s. I have to find time t2, acceleration in t2 (a2) and distance s2. I also have to draw a, v, t diagrams.
m2v⃗ -m1v⃗ 1=∫F(t)⃗ dt
The Attempt at a Solution
my formula in mathcad
I'm stuck with this integration. I understand that the first part (F*cos(60°)) is the area under the curve - √2 *m*g
I hope you guys can help. Thank you in advance.
