Answer:
it it the highest or lowest point of a parabola
Answer:Answer:
F = 0.84 [N]
Explanation:
In order to solve this problem we must take into account Newton's second law, which tells us that the sum of all forces applied on a body must be equal to the product of the mass of the body by its acceleration.
F = m*a
where:
F = force [N]
a = acceleration = 1.4[m/s^2]
m = mass = 0.6 [kg]
F = 0.6*1.4
F = 0.84 [N]
Answer:
230 mph in 2 hours
Step-by-step explanation:
first i found out how many miles does the train travel in one hour
460 miles ÷ 4 hours
= 115 mph / 115 miles in one hour
the question asks what was the speed of the train when it completed half the distance
half the distance = 1/2 of 460 =230 miles
230 miles is half the distance of the trip
& we know this is correct because earlier we found out that the train travels 115 miles in one hour & in 2 hours it travels 230 miles
115×2=230.
the one thing that i dont quite know is if you say the train is traveling 115 mph or 230 miles in 2 hours .im not sure of tnat .
Answer:
x=9
y=2
z=1
Step-by-step explanation:
xx+yy=zyz
xx can be divided by 11
yy can be divided by 11
zyz can be divided by 11
3 digit multiples of 11
110
121
132...
121=zyz because z=1 and y=2
121-22=99
xx=99
x=9
z=1
y=2
