A man walks 80 m to the left then 330 m to the right. Calculate the total displacement of the man250m due east
How do you calculate resultant of two vectors at right angles?Calculate the magnitude of the resultant using Pythagoras Calculate the direction of the resultant using trigonometry
Calculate the resultant displacement from this diagram. (HINT: 3, 4, 5 triangle)5m at 36.9° west of north
What is speed?Distance travelled in one second
What is the formula for average speed?V=d/t
In the below formula, what is v?average speed
In the below formula, what is d?distance
In the below formula what is t?Time
What is velocity?displacement in one second
What is the formula for average velocityv=s/t
In the below formula, what is s?displacement
In the below formula, what is t?time
How do you calculate average velocity?In the formula v=s/t, sub in magnitude of displacement only and sub in time Calculate the angle separately
What is instantaneous speed?the speed of an object at a particular moment in time
What indicates instantaneous speed in a car?speedometer
If given the equipment below, describe how to find instantaneous speed.A light gate consists of a light source + photocell. The photocell is connected to an electronic timing device. The timing device is triggered when the light beam is broken by the card. The timing device records how long the beam is blocked for. You then use "instantaneous speed=length of card/time beam is broken" to calculate instantaneous speed.
what is displacement?the straight-line length and direction between two points
