Form 2 Test 2 10

The document contains information about a cyclist completing 10 laps around a 500m track. It provides data about the cyclist's speed, distance traveled, time to complete laps, and acceleration during a spurt. It also includes questions about measuring instruments, errors in measurement, graphing speed over time for two cyclists, and a race between a runner and car with increasing speed. The summary is assessing speed, distance, time and acceleration from data provided about a cyclist over multiple laps of a track.

Form 2 Test 2 10/02/2017

1. A cycle track is 500 metres long. A cyclist completes 10 laps (that is, he rides completely round the track
10 times).
a Define i Speed ii distance [2]
b How many kilometres has the cyclist travelled? [2]
c On average it took the cyclist 50 seconds to complete one lap (that is, to ride round just once).
i What was the average speed of the cyclist? [2]
ii How long in minutes and seconds did it take the cyclist to complete the 10 laps? [2]
d Near the end of the run the cyclist put on a spurt. During this spurt it took the cyclist 2 seconds to increase
speed from 8 m/s to 12 m/s. What was the cyclist’s acceleration during this spurt? [2]

2. Copy and Complete the table below

Prefix Symbol Value

106

[6]
3. What instruments are used to measure
a Diameter of a wire
b Mass of an apple
c Current flowing in a circuit [3]

4. A student uses a rule to measure a thin piece of wire as shown below

The student records the length of the wire as 12.8 cm.


a State two errors in the student’s measurement of the length of wire. [2]
b The student is asked to measure the thickness of the wire using the same ruler. The student does this by
bending a short length of the wire and measuring distance x as shown below
i Use the ruler above to determine the distance x. [2]
ii Calculate the average thickness of the wire, in mm. Give your answer to two significant figures [3]

5 Two cyclists, A and B, are riding their bicycles on a flat and straight road. The graph shows a speed-time
graph for the first part of their journey.

a State the speed of cyclist B. [1]


b Calculate the distance travelled by cyclist B during the first 20 s. [2]
c Determine the time for which cyclist A was accelerating. [1]

Form 2 Homework 5

1 At a sports event, a champion runner and a car take part in a race.


(a) The runner runs at a constant speed of 10 m / s from the start of the race. During the first 5.0 s
of the race, the car’s speed increases from 0 m / s to 25 m / s at a uniform rate. Draw and label on the same
axis
i a graph to show the motion of the runner,
ii a graph to show the motion of the car. [8]
(b) Use your graphs to determine
i the distance travelled by the runner in the 5.0 s, [2]
ii the distance travelled by the car in the 5.0 s, [2]
iii the time at which the car overtakes the runner. [2]
