Acceleration-time (\( a \) vs. \( t \)) graph of a body is shown in the figure. Corresponding velocity-time (\( v \) vs. \( t \)) graph is:
A car accelerates from rest to a speed of 20 m/s in 10 seconds. What is its acceleration?
A ball is thrown vertically upward with a speed of 49 m/s. How long will it take to return to the thrower’s hand?
A particle starts from rest and accelerates uniformly at 4 m/s\(^2\). What is the distance covered in the 5th second?
A body starts from rest and moves with constant acceleration. If it covers a distance of $ 40 \, \text{m} $ in 4 seconds, then its acceleration is:
The acceleration-time graph of a particle moving in a straight line is shown in the f igure. If the initial velocity of the particle is zero, then the velocity-time graph of the particle will be:
Ques Fig

A particle is moving along x-axis with its position ($ x $) varying with time ($ t $) as:  
$ x = \alpha t^4 + \beta t^2 + \gamma t + \delta. $  
The ratio of its initial velocity to its initial acceleration, respectively, is:
