SUMMARY
The final velocity of a block sliding down a ramp can be calculated using the parameters provided: a height of 8m, a mass of 4.5kg, a coefficient of friction of 0.19, and an incline angle of 29 degrees. The acceleration due to gravity is 9.8m/s². The correct approach involves calculating the length of the incline and using the kinematic equation v² = u² + 2as, where the initial velocity (u) is 0. The acceleration (a) must account for both gravitational and frictional forces to determine the accurate final velocity.
