Questions
A plane is flying horizontally at 98m/s and releases an object which reaches the ground in 10s. The angle made by it while hitting the ground is:
detailed solution
Correct option is B
Vertical component of velocity of the object while hitting the ground is vy=0+gt =9.8×10=98m/s So the angle made by the object with the horizontal while hitting the ground.α=tan−1(vyvx)=tan−1(9898)=450 (∴ux=vx=98m/s)Talk to our academic expert!
