Answer:
v= 6.44 m/s
Explanation:
Given that
L= 10 m
θ = 12°
The block slides due to gravitational force.
The gravitational force along the incline ramp = m g sinθ
Lets take a is the acceleration of the block along the ramp
m a = m g sinθ
a= g sinθ
The equation of motion along the incline plane
Lets take final speed = v m/s
Initial speed u = 0 m/s
v²= v² + 2 a L
v²= 2 x g sinθ x L
v² = 2 x 10 x sin12° x 10 ( take g =10 m/s²)
v² =41.58
v= 6.44 m/s
