How long would it take you to swim across a lake that is 900 meters across if you swim at 1.0 ms2?
1 m/s² (1 metre per second per second) is a measure of acceleration, NOT speed. Assuming you mean a swim rate of 1.0 m/s (1 metre per second), then: time = distance ÷ speed = 900 m ÷ 1 m/s = 900 s 60 s = 1 min → 900 s = 900 ÷ 60 min = 15 minutes ---------------------------------- Assuming you really do mean that you swim with a constant acceleration of 1 m/s² and you start at 0 m/s, then: s = ut + ½at² s = 900 m u = 0 a = 1 m/s² t = unknown → 900 m = 0 m/s × t + ½ × 1 m/s² × t² → 900 m = ½t² → t² = 1800 s² → t ≈ 42.43 s If you start at 0 m/s and accelerate at 1 m/s², then it will take approx 42.43 seconds to cover 900 m.
What is constant accelaration?
M/s -1 - For example gravity has a constant acceleration of 9 M/s -1
What does the phrase 1 meter per second mean?
It's a measure of acceleration. It means something is gaining 1 m/s of speed every second it accelerates.
What is the value of 9.8M per s' 2?
The acceleration due to gravity on the earth, known as g, is 9.8m/s2 or 9.8m/s/s, which means that a falling object falls with an increasing velocity of 9.8m/s every second, or 9.8m/s/s, which means 9.8 meters/second/second. m/s/s can be written as m/s2, because m/s/s means m/s ÷ s/1 = m/s x 1/s = m/s2.
Spaceship 1 and Spaceship 2 have equal masses of 200 kg They collide Spaceship 1's final speed is 2 m/s, and Spaceship 2's final speed is 1 m/s in the same direction What is their combined momentum?
600kg-m/s apex miles
Why does metres per second have a -1 (m s -1)?
That's not s-1 , its s-1 . ... It indicates a reciprocal , so its the same as m/s.
What is the unit of thermal conductivity?
unit of thermal conductivity in SI system (W/m K)W/(mK) = J s^-1 m^-1 K^-1= kg m^2 s^-2 s^-1 m^-1 K^-1= kg m s^-3 K^-1

How can you derive the unit of frequency from basic units?
If the wave speed is measured in m/s, the wave length is measured in m, and the wave speed divided by the wave length = the frequency, then: m/s / m = 1/s thus the unit of frequency is 1/s or s^-1
What is constant accelaration?
M/s -1 - For example gravity has a constant acceleration of 9 M/s -1
If a car travles 65 km in 1 hour what is its average speed in meters per second?
1 km = 1000 m 1 hr = 3600 s → 65 km/1 hr = 65 × 1000 m/3600 s = 18 1/18 m/s = 18.0555... m/s ≈ 18.06 m/s
1 kg watt is equal to how many newtons?
I don't think there is any equivalency.... A watt isW = J/s = (N*m)/s = ((kg*(m/s^2))*m)/s = kg*(m^2))/(s^3)Therefore: W*kg = (kg^2)*((m^2)/(s^3)) which is not equal to N = kg*(m/s^2)I guess the closest answer would be :1 kg*W = (1 kg*m/s) N or1 kg*W = (1 N*s) N
What speed is mach 5?
mach 5 = 1 701.45 m / smach 5 = 1 701.45 m / smach 5 = 1 701.45 m / smach 5 = 1 701.45 m / smach 5 = 1 701.45 m / smach 5 = 1 701.45 m / s
How do you find equation for a pyramid of oranges stacked 1 2x2 3x3 4x4?
The equation for n layers is S(n) = n(n+1)(2n+1)/6It is simplest to prove it by induction.When n = 1,S(1) = 1*(1+1)(2*1+1)/6 = 1*2*3/6 = 1.Thus the formula is true for n = 1.Suppose it is true for n = m. That is, for a pyramid of m levels,S(m) = m*(m+1)*(2m+1)/6Then the (m+1)th level has (m+1)*(m+1) oranges and soS(m+1) = S(m) + (m+1)*(m+1)= m*(m+1)*(2m+1)/6 + (m+1)*(m+1)= (m+1)/6*[m*(2m+1) + 6(m+1)]= (m+1)/6*[2m^2 + m + 6m + 6]= (m+1)/6*[2m^2 + 7m + 6]= (m+1)/6*(m+2)*(2m+3)= (m+1)*(m+2)*(2m+3)/6= [(m+1)]*[(m+1)+1)]*[2*(m+1)+1]/6Thus, if the formula is true for n = m, then it is true for n = m+1.Therefore, since it is true for n =1 it is true for all positive integers.
In an isolated system Bicycle 1 and Bicycle 2 each with a mass of 15 kg collide. Bicycle 1 was moving to the right at 1 ms while Bicycle 2 was moving to the left at 3 ms. What is the magnitude of thei?
60 kg-m/s Just took the test
How do you calculate the cost if you know the selling price and mark up percent?
If the selling price is S and the Mark-up is M% then the cost, C*(1 + M/100) = S So that C = S/(1+M/100) = 100*S/(100 + M)
What does the phrase 1 meter per second mean?
It's a measure of acceleration. It means something is gaining 1 m/s of speed every second it accelerates.
