Vector When It Is Moving Parallel To The Vector I 2j D Acceleration Vector 2 A Particle Is Moving In The 1 J P 1 (78.97 KiB) Viewed 29 times

vector when it is moving parallel to the vector i - 2j, (d) acceleration vector. (2) A particle is moving in the 1 - j plane with an acceleration of (1 - - t)i + tý where t is the time. The particle is projected from the origin with an initial velocity of 3/2ims. Find the displacement of the particle at time t and the value of t when it is moving in the direction of motion. What is the angle between its velocity and displacement at this time? (3) The position vector r of a particle at time t is = 2t’i + (t? – 4t)j + (3t – 5)k. Find the velocity and the acceleration of the particle at time t. Show that when t = 2/5 the velocity an the acceleration are perpendicular to each other. The velocity and the acceleration are resolved into components along and perpendicular to the vector - 3; + 2k. Find the velocity and acceleration components parallel to this vector when t = 2/5. 2:03 PM 32°C Light rain hp
