What is the acceleration of the particle at t = 3 sec.
The displacement of the particle in the interval t = 5sec to t = 8sec is.
The particle reaches its maximum positive x-position.
From the top of a multi-storeyed building 40 m tall, a boy projects store vertically upwards with an initial velocity 10 ms–1 such that it eventually falls to the ground. After how long will the stone strike the ground? Take g = 10 ms–2.
