1. Answers to Problem Sheet 7
Physics – Equations of Uniform Motion

2. 2)
Velocity in m/s 30
450 45 3 18
Time in s

3. 2) cont….
Velocity in m/s 22
Answer fits here to fill in the unknown!
347.6
24.2
2.2 18
Now work out the total area under graph for distance travelled = 371.8
Time in s

4. 3) Is solved using simultaneous equations
Velocity in m/s
In a 100m race we know total s = s1+s2 v S2 S1
1.5
10.49
Time in s
Set up two equations one for each part of journey
Add together and should = 100m
As final “V” is the same for both sub into equation for s
Velocity v is found
