A rocket with mass 3030 kg is fired from rest from the ground at an elevation angle of 58.0° The motor exerts a thrust of 61.2 kN at a constant angle of 58.0° with the horizontal for 48.0 s and then cuts out. Ignore the mass of fuel consumed and neglect aerodynamic drag. Calculate (a) the altitude of the rocket at motor cut-out and (b) the total distance from firing point to impact.
Round off to two significant figures,Round off to three significant figures,vx = 514 m /s The horizontal distance travelled in time t1 is:The total horizontal distance say x travelled by the rocket is:Therefore the total horizontal distance travelled by the rocket is 5.88 x 104 m.
