Question

The Answer please send ​

Answer 1

Let, the angle of inclination =x

then,

tan(x)=

(rg)

v

2

( Can be obtained easily when F.B.D is drawn)

So, in this situation we can take

for very small angle x,

we can take

sin(x)=tan(x) ........ (almost equal)

=>

10

1.5

=

(50×9.81)

v

2

=>v

2

=0.15×50×9.81

=>v=

73.575

=8.575m/sec
