The 'x' component of the vector is given by
a cos (angle) = 1 cos 10 = .9848
The 'y' component is
a sin (angle) = 1 sin 10 = .1736
1/5 divided by 6500.... use calculator to get 0.000030769 or 3.0769 x 10^(-5)
x = smaller number
x+1 = next consecutive number
x + (x+1) = 87
2x + 1 = 87
2x = 86
x = 43
pi x 1^2 = pi
(pi x 1)^2 = pi^2
Speed is in units of distance/time
Displacement is 'distance'
and duration is 'time'
Use p = momentum = m x v 20 x 30 = kg m/s
Slope is rise/run
Use (y1-y2) / (x1 - x2)
(-3 -(-2) 0 / (-7 -(-1)) = -1 / -6 = 1/6 = slope
2 / 5
Tan (angle) = 7.6/18.2
angle = 22.66 degrees
Assuming the sing is full at the start, 3 U.S. gallons = 11,356.24 ml
11356.24 ml / 85 ml/10min = 1336 minutes to empty (also assuming a constant drip rate)
