Sprinters
Take the following text and use it to produce a table of velocity and time. Then
plot a velocity time graph and work out the race distance.

reach her top speed of 10 m/s.
She ran at this speed for 10
seconds.
She was running at 8 m/s when
she finished.

Cheetah HuntUse the velocity time data to plot a graph.
Mark points of acceleration, deceleration and steady speed.
Change the data into a brief description of the hunt.
Calculate the acceleration and deceleration of the cheetah.

Tachograph
By law HGV’s must have a tachometer and produce
tachographs. This monitors journeys driven in the truck to
ensure the driver is acting safely.
Q1. What type of graph is
a tachograph?
Q2. What time did the
driver start and end
work?
Q3. When did the driver
have lunch?
Q4. What was his top
speed?
Q5. What was the longest
journey he travelled?
A) in time
B) in distance
(estimate both)
