Answer:
s= 0.11 m
Explanation:
Given that
m = 6.6 kg
Initial velocity ,u= 1.51 m/s
Angle ,θ = 26.4°
Coefficient of friction ,μ = 0.57
The final velocity of the block = 0 m/s
s=Distance cover by block coming to rest
Now by using energy conservation
2 s (μ g cosθ + g sinθ) = u²
2 x s x 10 (0.57 x cos26.4° + sin26.4°) = 1.51²
Now by solving above the equation
we find ,s= 0.11 m
Therefore the answer will be 0.11 m.
