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
If a small lead ball falls from a high tower on Earth what will be its velocity after 2 seconds?
v = a X t. a = 9.8 m/s2 (acceleration) and t = time. At t = 2 seconds, v = (9.8 m/s2) X (2 s) = 19.8 m/s. At t = 4 seconds, v = (9.8 m/s2) X (4 s) = 39.6 m/s. [ANSWER: at t = 2 s, v = 19.8 m/s ; at t = 4 s, v = 39.6 m/s. ]
What is 9.8 m s2?
9.8 m/s 2
What is the acceleration of a car that slows down from 60 ms to 40 ms during a period of 10 seconds?
-2 m*s^-2 Also, your units are wrong it is m/s, not ms.
A sports car is advertised to be able to stop in a distance of 50 m from a speed of 90 What is its acceleration in m-s 2 how many G's is this?
d=50m Vi=90km/h(25 m/s) Vf=0 changing km/h to m/s--> 90x1000/3600= 25 Use: Vf^2= Vi^2+2ad 0^2= 25^2+ 2a50 = -81 m/s^2
Why is it s in the formula for acceleration has the exponent of 2?
m/s^2 ? , strictly speaking this should be (m/s)/s , meaning velocity change per second, so if you go from 0 to 10 m/s in 2 seconds , your acceleration is 10/2 = 5 (m/s)/s maybe m/s^2 is easier to type ?
How to find the side of the square with an area of 256m squared?
A = s^2 256 m^2 = s^2 √(256 m^2) = √(s^2) 16 m = s Thus, the side of the square has a length measure of 16 m.
What is the unit of E in E equals mc2?
Units Units of 'E' are kg m^2 s^-2 or kg(m/s)^2 or kg m^2 / s^2 or kg m ( m/s^2) In words it is a mass(kg) multiplied to distance (m) multiplied to acceleration (ms^-2). When Basic S.I. units are arranged in this manner they are referred to a Joules.

What is 3.7ms2?
3.7 m/s/s or m/s^2 Approximately the force of gravity on the surface of mars. On earth it is about 9.8 m/s/s.

A car goes from 16 m/s to 2 m/s in 3.5 s. What is the car’s acceleration?

Acceleration of gravity in meters per square second?
9.80665 m/s^2 Depending on where you are on the earth's surface the acceleration of gravity can vary by about 0.1 m/s^2. The average on earth though is taken to be 9.80665, in physics calculations 9.81 m/s^2, 9.8 m/s^2, or even 10 m/s^2 are often used. Note: 10 m/s^2 is actually a fairly good approximation and can speed up calculations significantly.
What is 9.8 m s2?
9.8 m/s 2
When walking to school you approach an intersection and slow down from 2 m s to a stop in 3 s What is your acceleration during this time interval?
Acceleration is change in velocity over time. In the metric system it is measured in meters per second per second (m/s squared). To figure it out, subtract the initial speed from the final speed and divide the difference by the time. In your example, 0 m/s - 2 m/s = -2 m/s. -2 m/s divided by 3 s = -2/3 m/s squared. Because the answer is a negative number, it is a deceleration - a slowing down.
What is the acceleration of a car that slows down from 60 ms to 40 ms during a period of 10 seconds?
-2 m*s^-2 Also, your units are wrong it is m/s, not ms.
Spaceship 1 and Spaceship 2 have equal masses of 300 kg They collide Spaceship 1's final speed is 3 m/s, and Spaceship 2's final speed is 2 m/s in the same direction What is their combined momentum?
