It would be more than it was but by how much would be 9
Answer:
Time, t = 10 seconds
Explanation:
Given the following data;
Mass = 10kg
Force = 10N
Final velocity = 10m/s
Initial velocity = 0m/s
To find the time;
First of all, we would find the acceleration of the box.
Force = mass * acceleration
10 = 10 * acceleration
Acceleration = 10/10 = 1m/s²
Now, we can find the time by using the first equation of motion;
V = U + at
10 = 0 + 1t
10 = t
Time, t = 10 seconds
Therefore, it will take 10 seconds for the box to come to a complete stop.
Answer: A reference point
Explanation: If an object is in motion then its distance from another object is changing. Whether an object is moving or not depends on your point of view. For example, a woman riding on a bus is not moving in relation to the seat she is sitting on, but she is moving in relation to the buildings the bus passes. A reference point is a place or object used for comparison to determine if something is in motion. An object is in motion if it changes position relative to a reference point. You assume that the reference point is stationary, or not moving.
Because they have special tool's that help them find out
Answer: Fourth option. It increased by a factor of 3.
Solution:
m1=1.0 kg
Cylinder's gravitational potential energy: Ep=m*g*h
Ep1=(1.0 kg)*g*h
Ep1=g*h
m2=3.0 kg
Ep2=(3.0 kg)*g*h
Ep2=3*g*h
Replacing g*h by Ep1 in the equation above:
Ep2=3*Ep1
Then, the cylinder's gravitational potential energy increased by a factor of 3.
