A particle moves over a plane with a constant acceleration . At the time the velocity is The speed of the particle when it is displaced by parallel to the -axis is,
- A
- B
- C
- D
Answer & Solution
Correct Answer
(A)
Step-by-step Solution
Detailed explanation
According to the second equation, of motion, in terms of initial velocity and uniform acceleration, s=ut+12at2, the displacement is given, s=6 m, 6=4t+124t2⇒2t2+2t-62=0⇒t2+2t-3=0 Now find the root of the above equation, ⇒t=-2±4+122=1 s then the…
