Waec Model Questions Vol1 2020 Physics Question 4
Practice practical question 4 from the 2020 Waec Model Questions Vol1 Physics examination. This question covers Forces .
A wooden block of mass 0.500 kg is placed on a long wooden plank that can be inclined. The coefficient of static friction between the block and the plank is to be determined experimentally. The experiment is performed in two stages: 1. The plank is slowly raised until the block just begins to slide. The angle of inclination at this instant is recorded as θ₁. 2. The plank is then set at a fixed angle θ₂ (greater than θ₁) and the block is released from rest. The time taken for the block to travel a measured distance of 1.00 m down the incline is recorded as t. Given the following data: θ₁ = 22.0° (to the nearest 0.1°)\nθ₂ = 30.0° (to the nearest 0.1°)\nt = 1.85 s (average of three trials).
