A particle moving along the xx-axis has its position described by the function x=(4t3+5t+2)mx=(4t3+5t+2)m, where t is in s.
At t = 2 s, what is the particle's velocity
At t = 2 s, what is the particle's acceleration?
A particle is moving along a straight path with a velocity v=2x(m/s). Here x is the path taken as m. At the first instant of t=0, x=0.5 m. How long does it take for the particle to reach the position where x=3 m?
A particle moves along the x-axis according to the equation x(t) = 2.0 − 4.0t2 m. What are the velocity and acceleration at t = 2.0 s and t = 5.0 s?
