Initially, a bicycle is at the position 7 = (130 m)i + (210 m)j. After 120 s, the position of the particle is 7 = (110 m)i + (240 m)j . What is the average velocity vector of the bicycle in that time
||
tinterval?
O Tav = (0.17 m/s)i + (-0.25 m/s)j
O Jay = (0.25 m/s)i + (-0.17 m/s)
O Tay = (-0.25 m/s)î + (0.17 m/s)
O Jay = (-0.17 m/s)i + (0.25 m/s)j
The velocity vector of a particle is given by:
V = Vje-)[sin(wt)i + cos(wt)j]
where, Vo = 12.1 m/s; T = 2.5 s; w = 5.2 rad/s
Calculate the magnitude of the acceleration (in m/s2) at t = 7.4 s
A snowmobile is originally at the point with position
vector 26.5 m at 95.0\deg counterclockwise from the x
axis, moving with velocity 4.85 m/s at 40.0\deg. It
moves with constant acceleration 1.86 m/s2 at 200\deg
. After 5.00 s have elapsed, find the following.(a) its
velocity vector v = m/s(b) its position vector r = m
