A projectile is launched at a velocity of v = 30 i + 35 j + 40 km/s from the origin of a Cartesian coordinate system, as shown in the figure, where i, j and k are versors aligned with the axes respectively. After a period of 3 seconds, a laser gun is fired at the projectile from the origin. Calculate the azimuthal angle a and the elevation angle in degrees in which the laser should fire in order to hit the target assuming no air resistance on the projectile. Please use g -9.81m/s. The angles a and The angles a and a: 19.9 are defined in the figure. are defined in the figure. Projectile trajectory Enter your answers below in degrees to three significant figures: 0 Laser line
