Question

QUESTION 4 For the motion of a projectile with no air resistance. How does total flight time change if you double the mass of your projectile? The time of flight is doubled. The time of flight is halved. The time of flight is the same for both masses. The time of flight decreases proportionally to the inverse of the mass. QUESTION 5 Which of these quantities stay constant for the 2D motion of a projectile with no air resistance? Acceleration Vertical Component of Velocity Horizontal Component of Velocity Horizontal position

Answer 1

8:47 we know, total flight time of a projectile is, 2N sino TAY IT = 2 where, v= Initial velocity at which projectile is thrown, angle with x axis at which it is thrown It will calculated bry, y= vigt-Y₂872 Vig av sino y=0. at t=T. T = avsino g is same is no mass dependence. so it u So there is the same for both The time of flight them marses. tenis

8:51) A In projectile motion thore is no accelaration along horizontal. So, velocity along horizontal is remain constant Am: - Horizontal component of velocity
