If the angle of the projection make Double with keeping same velocity of projection then find the final range? |
|
Answer» Explanation: We know MAXIMUM height of a PROJECTILE motion is given by H = 2g v 2 sin 2 θ
Thus from the relation we can say maximum height of the projectile motion depends on squre of VELOCITY of the projectile directly. Thus doubling the velocity will quadraple the maximum height if the angle of projectile REMAINS same. |

Kindly answer this wrong answer will be reported |
|
Answer» The initial velocity of the PROJECTED OBJECT is given as: v0=15iˆ+20jˆv0=15i^+20j^ There is acceleration in the vertical direction only. There is no acceleration in the HORIZONTAL direction, so the velocity in the horizontal direction will remain the same. Therefore, the velocity in the horizontal direction after t = 2 s, vx = 15 m/s Using equation of motion, let us find the velocity of the object in vertical direction after t = 2 s: vy = uy -gt vy = 20 - 9.8×2 = 20-19.6 = 0.4 m/s Therefore, the velocity of the particle after 2 s, v=vxiˆ+vyjˆ=15iˆ+0.4jˆ Explanation: |
