The minimum speed required is 3.68 m/s.
What is friction ?
A force called friction prevents mobility between any two contacting surfaces. We can use friction for or against us. For instance, adding sand to an icy pavement improves friction, which makes slipping less likely.
If there is no friction, energy conservation can be used. The ramp will switch KE for PE as the puck rises.
It will have just enough KE at the bottom to ascend, so:
0.5 mv^2= mgh
0.5 v^2 = gh
v =SQRT(2gh)
=0.69
so,
v= SQRT(2*9.8*0.69)
v= 3.68 m/s
