Projectile Problems – Type 2: 1. The photograph below shows a basic projectile at several locations on its trajectory.

a) List the location(s) where the vertical component of the velocity would be zero.

b) What is the vertical component of the acceleration at location #3?

c) What is the horizontal acceleration of the projectile?

d) Identify the location where the vertical displacement would be zero.

e) Identify the location with the maximum displacement.

f) Rank each location in terms of the projectile's speed (highest to lowest).

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)

You and a friend (alex) are at a a tree-top adventure park .. . part of the course requires you to climb up a rope. you both climb the same rope in the same amount of time. however, the tension in the rope is greater when alex climbs. who did the most work? alex did - more tension means more force - more force means more work was done you did - less tension means less force - less force means more work was done to find the work done, the force exerted and distance moved are multiplied. a couch is moved twice before you are happy with its placement. the same force was used to move the couch both times. if more work is done the first time it is moved, what do you know about the distance it was moved? when more work was done, the couch was moved less. when more work was done, the couch was moved further. when more work was done, the couch wasn't moved at all. when more work was done, the couch was moved the same distance.

Suppose a comet has an orbital period of 309.1 years around the sun. what is it’s average distance from the sun?
