A particle is moving along the x- axis with its coordinate with time 't' given by . Another particle is moving along the y-axis with its coordinate as a function of time given by At s, the speed of the second particle measured in the frame of the first particle is given by . Then (in m/s) is ____________.
A particle starts from the origin at t=0 with an initial velocity of and moves in the x-y plane with a constant acceleration The x-coordinate of the particle at the instant when its y-coordinate is 32 m is D meters. The value of D is :
The sum of two forces and is such that The angle (in degrees) that the resultant of and will make with is ,
