Its initial speed cannot be 20 m, as stated in the question. Secondly, if the initial speed is correctly given, then there is no need to calculate it!
125 divided by 2 = about 62.5 62.5 mph
125 divided by 2....
Not enough information. You also need to know how much the acceleration is. Once you know that, calculate the final speed, then calculate the average speed as (initial speed + final speed) / 2, and multiply that by the time to get the distance.
wind speed = squrt(u^2+v^2).
1) I learned that you can have as many variables as you want. 2) You can change the variables. 3) Variables is used in an experiment. 4) A variable is something that can be changed, such as a characteristic or value. Variables are generally used in Psychology experiments to determine if changes to one thing result in changes to another.
Distance travelled/Time taken.
4(x-1)2(x2+6x+8) and 10(x-1)(x+2)(X2+7x+10)
If both speeds are used for the same amount of time, the average speed is just the sum of the two speeds divided by 2. If one speed is used for a longer time than another, you will have to calculate the total distance traveled for each speed (speed x time), and then divide by the total time (add the times).
Twenty miles an hour
variables are used to substitute for an unknown number. john is 10 years old. harry is 2 years older than him. 10+2=x x=12
It doesnt, it's saying that Energy=the speed of light^2 (the ^2 stands for squared) which can be used to calculate scientific junk, and I may not be right about the e=energy part
times by 2
If a car travels 200 km in 2 hours, it will be traveling at the speed of: 200 km/2 hours = 100 km/h (62 mph)
"Speed 2" (except a boat was used in lieu of a bus).
2m*0.3Hz=0.6m/s
