How do you find the displacement of a particle?

[SOLVED] The displacement of a particle is given by x = ( t – 2 )^2 where x is in metres and t is in seconds. The distance covered by the particle in first 4 seconds is

What is the distance covered by the particle in first 4 seconds?

The displacement of a particle is given by x = (t – 2)^2 where x is in metres and t in seconds. The distance covered by the particle in first 4 seconds is (a) 4 m See what the community says and unlock a badge. displacement at t =0 is : x = 4 meters… displacement at t = 2 sec is x = 0 meters..

What is the velocity and acceleration of the particle after 2 seconds?

Ans: The velocity and acceleration of the particle after 2 seconds are – 9 units/s and 4 units/s 2 respectively. A particle is moving in such a way that is displacement’s’ at any time ‘t’ is given by s = 2t3 – 5t2 + 4t – 3.

How do you find the position of a particle on x axis?

A particle moves along the x-axis. Its position is given by the equation x = t2 – 3t + 2 with SI units. Determine (a) its position when it changes direction and (b) its velocity when it returns to the position it had at t = 0.

How do you find the equation of motion of a particle?

The equation of motion of a particle is given by x = 2 t 2 − t 3 . (a) Find the acceleration at t = 2 s (b) Is acceleration of the particle a constant. A block is kept on the floor of an elevator. The elevator start descending with an acceleration of 1 2 m / s 2.

What is the displacement at T2 and T4?

Now at t = 2, displacement is zero and at t = 4 displacement is 4 units. But because at v = 0 we have t =2 this indicate that velocity will decrease from v to 0 in 2 seconds, i.e velocity will not change its direction, thus in this case. distance = displacement.
