Questions and Answers

What is the position of the particle at time t = 0?

x = 4t | t = 0, so x = 0 m

Find the expression for velocity of the particle.

v = dx/dt = d(4t + l(1-t))/dt = 4 - l

What is the initial velocity of the particle?

v = 4 - l, when t = 0

Find the acceleration of the particle.

<p>a = dv/dt = d(4 - l)/dt = 0</p> Signup and view all the answers

What is the velocity of the particle at time t = 1.5 s?

<p>v = 4 - l, substitute t = 1.5 into the velocity equation</p> Signup and view all the answers
