Q. 18
A wooden block sliding down from the top of a smooth inclined plane starting from r takes ti, seconds to
reach the bottom of the plane and attains velocity V. Another block of twice the mass falling freely from
the same height takes t sec, to reach the bottom of the plane and attains V2. If angle of inclination the
plane is 30°
1) O
=v; &t, = 21;
2)
v = v, &t; = 1;
3) O
v=v, &t, = 21,
4) O v; > v; & , >,​

Answer 2

Answer:

The velocity attained will be same since the heights are same. But the acceleration for the vertical fall is g, and for the sliding wooden block it will be g sin30

o

=0.5g.
