5 分A toy car is released from rest at the top of a ramp. It travels a distance of \(1.5\text{ m}\) down the ramp with a constant acceleration of \(1.2\text{ m/s}^2\).
a) Calculate the final speed of the toy car at the bottom of the ramp. State the appropriate unit for your answer.b) Calculate the time taken for the toy car to travel the distance of \(1.5\text{ m}\) down the ramp.
c) A student wants to measure the final speed more accurately than using a ruler and a stopwatch. Describe how the student could use light gates and a data logger to measure the speed of the toy car at the bottom of the ramp.

第 10 题
6 分A lift starts from rest on the ground floor and moves upwards. Its motion consists of three stages:
Stage 1: It accelerates uniformly for \(4.0\text{ s}\) until it reaches a constant velocity of \(2.5\text{ m/s}\).
Stage 2: It travels at this constant velocity for the next \(6.0\text{ s}\).
Stage 3: It decelerates uniformly over the final \(2.0\text{ s}\) until it comes to rest at an upper floor.
a) Calculate the acceleration of the lift during Stage 1.
b) Determine the deceleration of the lift during Stage 3.
c) Calculate the total height (distance) moved by the lift from the ground floor to the upper floor.
