  7. 1.- A car iswaitingforthetrafficlightstoturngreen. Whenthishappens, the driver stepsontheaccelerator and the car reaches 80 km/h in 5 s. what´sthe car accelerationrate? 2.- A motorcyclistis travelling along a motorway at a spaeed of 120 km/h. Suddenlyshesees a maximunspeedsignfor 90 km/h ahead of her, so she reduces herspeedtothatvalue in 3s. Workouttheacceleration of themotorbike. 3.-A motorcyclistis travelling at 104km/h on a motorway. At a specificmoment, therider decides toovertake a car in fornt of him and increaseshisspeedto 120 km/h in 2 s. Whatistheaccelerationrate? 4.-A car travelling at a speed of 0 km/h comes to a complete stop in 5s whenthebrakes are pressed. Calculatetheacceleration. -5m/s2 2.25m/s2 -2.8m/s2 4,4m/s2

  8. UniformlyAcceleratedRectilinearMotion UARM is motion with a straight line trajectory and constant acceleration. The speed varies by the same amount in the same intervals of time.
