A butterfly is flying with velocity `10hati +12hatj m//s` and wind is blowing along `x` axis with velocity `u` . If butterfly starts motion from `A` and after some time reaches point `B`, find the value of `u`.

A bird is flying with velocity 5hati + 6hatj w.r.t wind and wind to blowing along x-axis with velocity u. if bird starts moving from A and after some after some time reaches point B (see figure), find the value of u ?

A butterfly is flying with a velocity 4 sqrt(2) m//s in North-East direction. Wind is slowly blowing at 1 m/s from North to South. The resultant displacement of the butterfly in 3 seconds is :

A body is projected vertically upwards with some velocity u . It at the same point at t = 6 s as was at t = 4 s . Find the value of u .

An object is projected with velocity vecv_(0) = 15hati + 20hatj . Considering x along horizontal axis and y along vertical axis. Find its velocity after 2s.

Three particles start from the origin at the same time, one with velocity u_1 along the x-axis, the second with velocity u_2 along the y-axis . Find the velocity of the third particles, along the x=y line so that the three particles may always lie on the same straight line.

An object is projected with velocity vecv_(0) = 15hatj + 20hatj . Considering x along horizontal axis and y along vertical axis. Find its velocity after 2s.
