Well, part of 'velocity' is the direction of the motion, and the graph doesn't give us any information about the direction. So the best we'll be able to do is find the average SPEED of the car.
On a distance/time graph, the speed is just the slope of the line. Since this graph is a straight line, it doesn't matter which points along the line you choose ... the answer will always be the same.
Average speed = (distance covered) / (time to cover the distance)
Let's use the ends of the line ... the origin, and the point at the top.
On the left side of the graph, we see the label 'Distance (m)', and I don't know what 'm' stands for. It could be 'miles' or 'meters'.
Anyway, the point at the top of the line shows that the car covered a distance of 25.0 'm' in 10.0 s of time.
Average speed = (25 m) / (10 s)
Average speed = (25/10) m/s
(I'm pretty sure that 'm' means 'meters' and 's' means 'seconds'.)
Answer:
x = 2.26 miles from the shore P i.e. point at which boat be landed.
Explanation:
x is the distance from point of landing i.e R and P
So, she cover a distance miles
She rows with a speed of 3 miles per hour.
So, time taken for rowing
She walks a distance = RQ = 14-x
She walks with a speed of 4 miles per hour.
So, time taken by the woman for walking \
Thus, total time taken
For total time to be least, T ' = 0
T '
x = 2.26 miles from the shore P
Momentum
perfectly elastic collision and m₁ = m₂, then:
v₁ = +2, v₂ = -3.6 (different direction)
v₁’ = v₂ dan v₂’ = v₁, then:
v₁' = -3.6, v₂' = +2
Answer:
1. A. is louder or softer
2. B. Has a different speed
Explanation:
Sorry if any or both are wrong
Answer:
Northeast
Explanation:
I'm not sure if there's some fancy thing you have to do, but if there's no cardinal compass given, I think it's safe to assume that the answer is based off of one. Therefore, up is north, right is east, so Maple Creek flows to the northeast.
However, if they do give you one where, say, north points downwards, the creek would flow to the southwest. But again, from what is shown, there's no compass, so NE is your best guess here.
