4. Motion In A Straight Line question bank (Physics)

The displacement of a particle is given by  
\( y = a + bt + ct^2 - dt^4 \)  
The initial velocity and acceleration are respectively:

The acceleration ‘a’ in \( \text{m/s}^2 \) of a particle is given by \( a = 3t^2 + 2t + 2 \), where \( t \) is the time. If the particle starts out with a velocity \( u = 2 \, \text{m/s} \) at \( t = 0 \), then the velocity at the end of 2 seconds is:
