FAQs

What is the correct statement about the acceleration of a car between 10s and 20s?
According to the document, the acceleration of the car between 10s and 20s is constant, but not zero. This is derived from the speed-time graph provided, which indicates that the speed is increasing steadily during this time interval.

How far does a student walk in 50 seconds at a constant speed?
The document states that a student walks at a constant speed, taking 100 seconds to walk 160 paces, with each pace measuring 0.80 m. Therefore, in 50 seconds, the student would walk 80 meters, calculated by determining the speed and then applying it to the shorter time frame.

What happens to the velocity and acceleration of an object falling under gravity?
When an object falls from rest, its velocity increases until it reaches terminal velocity. Initially, the acceleration is constant due to gravity, but as the object falls, air resistance increases, eventually balancing the weight of the object, resulting in zero acceleration at terminal velocity.

What is the average speed of a cyclist over a 25-second ride?
The document presents a scenario where a cyclist's distance from the starting position is plotted against time. To find the average speed for the entire ride, one must calculate the total distance traveled and divide it by the total time taken, which is 25 seconds.

What is the total distance traveled by an object accelerating from 10 m/s to 20 m/s?
The document describes an object that travels at a constant speed of 10 m/s for 10 seconds, then accelerates uniformly to 20 m/s over the next 5 seconds. The total distance can be calculated by finding the distance covered at constant speed and the distance covered during acceleration.

How does the speed-time graph indicate non-uniform acceleration?
In the document, a speed-time graph illustrates different sections of a car's journey. Non-uniform acceleration is represented by sections of the graph where the slope is changing, indicating that the acceleration is not constant throughout those intervals.

What is the average deceleration of a car brought to rest from 10 m/s in 5 seconds?
The document states that if a car is brought to rest from a speed of 10 m/s over a duration of 5 seconds, the average deceleration can be calculated using the formula for acceleration. In this case, the average deceleration would be 2 m/s².
