Please help me solve these question below in detail.

Is it clearlier now. It is Physic for grade 12 question.

1. A hang-glider launches herself from a high cliff and drifts 6.0 km south. A wind begins to blow from the southeast, which pushes her 4.0 km northwest before she lands in a field. Calculate her average velocity for the trip if she is in the air for 45 min. 2. A canoeist paddles across a calm lake with a velocity of 3.0 m/s north for 30.0 min. He then paddles with a velocity of 2.5 m/s west for 15 min. Determine the average velocity of the canoeist over the duration of the trip. 3. A car is traveling east at 45 km/h. It then turns, heading north at 50 km/h. Determine its change in velocity. 4. An airplane is flying at 2.00 x 10' km/h [S 30.0 W]. It makes a smooth wide turn and heads east at 2.00 x 10 km/h. Find its average acceleration. 5. In a movie, an actor runs horizontally off the roof of one building and lands on the balcony of a second building. The buildings are 6m apart and the landing spot (balcony) is 3m below the take off point (roof). How fast must the actor run to be able to make the jump? 6. A car driving at 17m/s careens off a cliff 38m high. Where does the car land? 7 . Find the range of an arrow shot at 42m/s with an angle of 40 from the horizontal. 8. Find the maximum height of a bullet shot at a 60 angle from the horizontal if the muzzle velocity of the bullet is 220m/s. 9. A ball is kicked in the air and lands on the ground at an angle of 550 from the horizontal, going 15.5m/s at the point of impact. Find the height of the ball's trajectory. 10. A kayaker paddles upstream in a river at 3.5 m/s relative to the water. Observers on the shore note that he is moving at only 1.7 m/s upstream. Determine the velocity of the current in the river
