Question 4 IJMB_MODEL_QUESTIONS_VOL1 • 2025 • PHYSICS • practical

A wooden block of mass 2.00 kg is placed on an inclined plane. Two spring‑scale sensors are used: Scale A is attached to the block by a light string parallel to the plane to measure the component of weight acting down the slope, and Scale B is placed between the block and the plane to read the normal reaction. The readings obtained are: • Scale A (parallel component) = 9.8 N • Scale B (normal reaction) = 16.9 N The block is then released from rest on the same plane. The coefficient of kinetic friction for the block–plane contact is known to be μ_k = 0.15.

Question Parts

( a )
Determine the angle θ of the inclined plane using the two scale readings.
( b )
Using the angle found in part (a), calculate the coefficient of static friction μ_s that would just prevent the block from moving when it is at rest on the plane.
( c )
With the kinetic friction coefficient μ_k = 0.15, compute the acceleration a of the block down the plane after it is released.
( d )
Assuming the block starts from rest, calculate the distance travelled along the plane in the first 2.0 s.
( e )
Suggest two experimental sources of error that could affect the determination of the angle and the acceleration.
