A pendulum consists of a 2.0-kg wooden block hanging on a 1.5-m length string. A 10-g bullet moving with a horizontal velocity strikes the wooden block (initially at rest) and embeds in the block, and the entire system swings through a height of h = 0.75 m. Answer the following questions a. Draw a diagram illustrating all the elements of the problem.
b. Find the initial speed of the bullet.
c. How much kinetic energy is released in this 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)

Often called simply "velocity," this is the velocity of an object at a particular moment in time.
