Kinematics Question 617

Question: A projectile is given an initial velocity of (i^+2j^)m/s , where; it’s along the ground and j it’s along the vertical. If g=10m/s2 , the equation of it’s trajectory it’s :

Options:

A) y=x5x2

B)y=2x5x2

C) 4y=2x5x2  

D)4y=2x25x2

Show Answer

Answer:

Correct Answer: B

Solution:

[b] From equation, v=i^+2j^

x=t …(i) y=2t12(10t2) …(ii) From (i) and (ii), y=2x5x2
