Abody 'a' of mass 1.5kg travelling along the positive x-axis with speed of 4.5m/s collides with another body 'b' of mass 3.2kg, which initially is at rest as a result of the collision, 'a' is deflected and moves in a speed of 2.1m/s in a direction which is at an angle of 30 degree below the x-axis. 'b' is set in motion at an angle φ above the x-axis. calculate the velocity of 'b' after the collision.

Alow cost, low earth orbit (leo) satellite is to be fabricated at a university, for subsequent launch by rocket. what are the constraints and objectives for selection of a material suitable for the satellite bus (i.e. the structure)? explain each in brief. (15 marks) b)suggest sources of data which could support the selection of materials for applications in space. (5 marks) c) set weights for the objectives listed in (2a) using the digital logic method. (5 marks)

What is a good example of instantaneous speed

You are given a vector a = 125i and an unknown vector b that is perpendicular to a. the cross-product of these two vectors is a × b = 98k. what is the y-component of vector b?
