The velocity of a particle as a function of time is given by v(t) = (2.3 m/s) + (4.1 m/ s 2 )t - (6.2 m/ s 3 )t 2 . What is the average acceleration of the particle between t = 1.0 s and t = 2.0 s? A. - 13 m/ s 2...
6 The velocity vm s' of a particle at time t s is given by v=t2-9. The particle travels in a straight line and passes through a fixed point O when t = 2.(i) Find the displacement of the particle from O when t = 0.[4](ii)Calculate the distance the particle travels fr...
5. A particle moves along the x-axis. At time t seconds, t 0, the velocity of the particle is3/2vms-1 in the direction of x increasing, where v = 2t- 6t + 2At time t= 0 the particle passes through the origin O. At the instant when the acceleration of the particle is ze...
定律1.the direction of velocity in curvilinear motion is changing with time and the direction of the velocity of a particle at a certain point(or instsnt)is in the tangent direction of the curve at that point.2.when the direction of the net force a body experiences and the direction of ...
