Question

A projectile is given an initial velocity 1i+3j.
If equation of trajectory is y=ax - 5x^b, find a+b
(given g = -10j)​

Answer 1

Answer:

ANSWER

The equation of projectile is given by

y=xtanθ−21u2cos2θgx2

Here,

tanθ=UxUy=12=2

Therefore,

y=2x−21(12+22)×1+tanθ110x2=2x−21(12+22)×5110x2

⟹y=2x−5x2
