The x and y coordinates of the particle at any time are x = 5t – 2t2 and y = 10t respectively, where x and y are in meters and t in seconds. The acceleration of the particle at t = 2 s is

• 0

• 5 m/s2

• -4 m/s2

• –8 m/s2

C.

-4 m/s2

x = 5t – 2t2    y = 10t

Acceleration of particle at t = 2 s is = –4 m/s2

x = 5t – 2t2    y = 10t

Acceleration of particle at t = 2 s is = –4 m/s2

Is absolute rest or absolute motion possible?

Absolute rest and absolute motion is not possible because there is no point in the universe which is at rest and can be taken as point of reference. The planet Earth is in continuous motion.

What is the most essential thing to study the motion of a body?

The most essential thing to study the motion is reference frame. Rest and motion are relative terms. It means that an object in one situation can be in rest but in another situation, the same object will be in motion.
