Answer:
120 miles
Explanation:
Speed = distance traveled/ time taken.
Distance traveled = speed * time taken
Speed = 40 miles per hour, time = 3 hours.
Distance = 40*3
The train's traveled distance is 120 miles.
The correct answer would be [ a spring scale. ]
I hope this helps!!!
Radio, speaker, drums, alarm clock Anything that makes a sound!
You're only asking 5 points for this question? it's kinda a lot :) just saying (i'm calculating it right now i'll comment the right answers)
Answer:
h (3) = 0
Explanation:
In this exercise they give us the expression that governs the movement
h (t) = 5 sin (2πt)
remember that the angles are in radians.
To calculate the instantaneous velocity we substitute
h (3) = 5 sin (2π 3)
h (3) = 0
therefore the body this is its position of equilibrium
