Answer:
0.25s
Step-by-step explanation:
As v = 1.5 cos(4πt), v is maximum when cos(4πt) is maximum = 1. So the maximum velocity would be 1.5 m/s
Both the lowest and highest position occurs when its derivative is 0, aka v = 0 and has a change of direction
1.5 cos(4πt) = 0
cos(4πt) = 0
4πt = π/2 and 4πt = 3π/2
t = 1/8 = 0.125s and t = 3/8 = 0.375s
So the time it takes to travels from 1 point of time (0.125s) to another point of time (0.375) is
Answer:
Step-by-step explanation:
Given that:
Speed of Wilmer up the hill = km/min
Time taken up the hill = minutes
Speed of Wilmer down the hill = km/min
Time taken up the hill = minutes
Distance can be calculated by multiplying the Speed with Time i.e.
The formula for distance is given as:
Distance up the hill =
Distance down the hill =
It is well known that, the distance up the hill and down the hill will be same.
Putting both the values equal, we get:
