Published on: August 13, 2026

Starting at time t = 0 from the origin with speed 1 ms -1 a particle follows a two-dimensional trajectory in the x-y plane so that its coordinates are related by the equation . The x and y components of its acceleration are denoted by a x and a y , respectively. Then

A
a x = 1 ms -2 implies that when the particle is at the origin, a y = 1 ms -2
B
a x = 0 implies a y = 1 ms -2 at all times
C
at t = 0, the particle's velocity points in the x-direction
D
a x = 0 implies that at t = 1 s, the angle between the particle's velocity and the x axis is 45°
