1 A car is travelling north with the cruise control on. The speed of the car is 100 km/h. 30 seconds later, the car is heading [N30'E], still travelling at 100 km/h. Determine: a) The average acceleration of the car b) The displacement of the car. 2 An air puck is given an initial velocity of 1.2 m/s [E40N]. It proceeds to accelerate at a rate of 0.40 m/s' [S] for 3.4 s. Determine the displacement of the puck during this time. 3 A figure skater collides with the boards on the rink at a point which is 25 m [560E] of where she started. If she hit the boards with a velocity of 4.5 m/s [E] after spending only 10.0 s on the ice, determine her average acceleration. 4 An electron enters a magnetic field with an initial velocity of 1.2 x 10* m/s [S]. It exits the field at a point which is 12 cm [S50E] from where it entered, only 9.8 ms later. Determine: a) The acceleration of the electron within the field. b) The velocity of the electron when it left the field
