Answer:
The equations are :
h = 18 + 1.5t
h = 5 + 24t - 16t^2
Explanation:
Speed = distance/time
1.5ft/s = 18ft/t
1.5t=18
The equation to determine height h= 18 + 1.5t
Graham moved another 5ft further with a velocity of 24ft/s
The equation to determine his height will be:
h= 5 + 24t -16t^2
Answer:
a) 
b) No
Explanation:
A) Because the electron is affected by an acceleration force in this case by the electric field, we can use the formulas of 2-dimension movement.
We will assume the electron missed the upper plate, so we need to calculate the time to travel all the way through the plate, that is:


so:

the electron experiences an accelerated motion in the vertical direction, so we can obtain the acceleration of the electron:

so:

now we can use the relation:


Now we can calculate the electric field:

B) Because the proton has the same charge but positive it will go in the opposite direction, so because we assume the electron didn't touch the plate, the proton won't.
Answer: D. Acceleration of Object A is twice of that of the acceleration of Object B.
Reaction time will stay the same for each person however the faster the car is going the faster someones reaction time would need to be react to something that happened. therefore it might seem like someone had a slower reaction time when a car is moving faster because everything happens faster when you are moving faster
