Question 1
A cheetah starts from rest and accelerates to a speed of 20m/s
in 10 seconds. What was its acceleration?
Question 2
A car accelerates from 5m/s to 25m/s in 10 seconds. What is its
acceleration?
Question 3
A pea was flicked across the table from rest to a speed of 14m/s
in 0.4 seconds. What was its acceleration?
What is the difference between accelerating and decelerating?
Question 4
Calculate the deceleration (in m/s2) of a train that is initially
travelling at 16 km/s but finishes travelling at a speed of 15km/s
in a time of 40 seconds.
What about your answer tells you the train is decelerating?
Question 5
A man travelling in a rocket powered sledge, decelerated from
284 m/s to 0 m/s in 15 minutes. What was his deceleration in
m/s2?
Question 6
Lewis Hamilton’s F1 car can accelerate from zero to 160
kilometres per hour in 0.86 seconds. What is its acceleration in
m/s2?
G-Force is the force acting on an object due to its acceleration
compared to that of the gravitational field (9.81m/s2). How many times
more than gravity is Lewis accelerating?
What effect do you think this could have on his body?
Question 7
Calculate the final velocity in m/s when a car travelling at 10 m/s
accelerates at 2 m/s2 for 10 seconds.
Question 8
A car accelerates at 7m/s2 for 2 seconds. If it is now travelling at
26 m/s, how fast (in m/s) was it travelling before accelerating?
