1. a car is driven east for adistance of52 km,then north for 33 km, and then in a direction32 degree east of north for 28 km.draw the vector diagram and determine the total displacement of the car from its starting point. and direction(counterclockwise from east. Q2. a plane diving with constant speed at an angle of 47 degree with the vertical, releases a projectile at an altitude of 540 m. the projectile hits the ground 5 s after release.(assume a coordinate system in which the plane is moving in the positive horizontal direction, and in negative vertical direction. no air resistance. (a) what is the speed of air craft? (b) how far did the projectile travel horizontally during its flight? (c) what were the horizontal and vertical components of its velocity just before striking the ground?
