3. Explain the following (using the concepts of moment, centre of gravity and stability.) a) Racing cars are low, with wide wheels. b) It is difficult to steer a bicycle by gripping the centre of the handlebars.

c because the action was the roller coaster reaches bottom of hill (action) reaction would be blood tends to drain away from head

hope this !

iron would move it is magnetic there is a mag field around the current in the wire

we're given that v₀ = 0 and a = 5.4 m/s². therefore, since v = at + v₀ for constant acceleration the equation for velocity is

after 28s,

m/s

which i would round to 150 m/s as my final answer
