Question

A particle starts from the origin at t=0 with an initial velocity of 3.0 im/sand moves in the x-y plane with a constant acceleration (6.0 i+4.0 j )m/s^2 The x -coordinate of the particle at the instant when its y -coordinate is 32m is D meters. The value of D is:

Accepted Answer

Correct answer: D. (d) S_y=u_yt+ 12a_yt^2 32=0+ 12 4t^2 ⇒t=4 sec S_x=u_xt+ 12a_xt^2 =3 4+ 12 6 16 =60m

$A particle starts from the origin at t = 0 with an initial velocity of 3.0 i^m / s and moves in the x - y plane with a constant acceleration (6.0 i^+ 4.0 j^) m / s^{2} The x -coordinate of the particle at the instant when its y -coordinate is 32 m is D meters. The value of D is:$
