Question

Question 1:

a) Describe projectile motion, making short notes on the definition of projectile motion, the trajectory of the object in motion, why and how this two-dimensional situation can be separated into two one- dimensional parts and give details on its horizontal and vertical velocity and acceleration.

b) While exploring a cave, a spelunker starts at the entrance and moves the following distances in a horizontal plane. She goes 76.0 m north, 251 m east, 123 m at an angle   30.0 north of east, and 153 m south. Find her resultant displacement from the cave entrance.

c) Describe the difference between a scalar and a vector quantity. Give 3 examples of each

d) A speed ramp at an airport is basically a large conveyor belt on which you can stand and be moved along. The belt of one ramp moves at constant speed such that a person who stands still on it leaves the ramp 64 s after getting on. Chris is in a real hurry, however, and skips the speed ramp. Starting from rest with an acceleration of 0.37 m/s2, she covers the same distance as the ramp does, but in one-fourth the time. What is the speed at which the belt of the ramp is moving
