Initial velocity of a particle moving along a straight line with const

1.	Initial velocity of a particle moving along a straight line with constant acceleration is 20+ or - 2 m/s, if it's acceleration us a= 5+ or - 0.1 m/s², then velocity of the particle with error, after time t in s is?
Answer» ANSWER: "+-" (and any subsequent words) was ignored because we limit queries to 32 words. Explanation: At time a particle is at It starts MOVING towards POSITIVE x-axis with CONSTANT acceleration (initial velocity=0). After 2 s, an additional acceleration of starts acting on the particle in negative y-direction also. FIND after next 2 s. (a) velocity and (b) coordinates of particle.

ANSWER:

"+-" (and any subsequent words) was ignored because we limit queries to 32 words.

Explanation:

At time

a particle is at

It starts MOVING towards POSITIVE x-axis with CONSTANT acceleration

(initial velocity=0). After 2 s, an additional acceleration of

starts acting on the particle in negative y-direction also. FIND after next 2 s.
(a) velocity and
(b) coordinates of particle.
