Homework Statement:

An initially stationary wooden block with a mass of 2kg is pulled horizontally along a time dependent force f(t)i. The coefficient of static and kinetic friction between the block and the table are 0.5 and 0.25 respectively. F(t) as a function of time is shown, then find
(i) if initial velocity of the block is zero, its velocity at 4 seconds will be ?
Relevant Equations:
 F=ma, f=(mu)N
Here's the given Ft graph
My Attempt.....
Fsmax=10N & Fk= 5N
I made equatiom F=5t5 ( by seeing Force force and Counteracting kinetic friction)
reduced the formula to a=(5tt)/2 wrote a=dv/dt and solved it but got wrong answer.
