The impulse exerted by a force F on an object in a time
is given by
In our problem, we have a force of 120 N: F=120 N, applied to the baseball for a time of
. Therefore the impulse is
I think it's 45 miles. Don't know for sure though
Answer:ans is b solids
Explanation: this is because molecules in a solid medium re much closer together than those in liquid or gas allowing sound waves to travel quickly through it
<span>This is the jet stream. This air current flows from west to east along a typically-meandering path that is often used as a predictor of weather conditions. These currents are typically formed from the fact that the equator is warmer than the poles, and this allows the different-density air masses to develop an eastward-moving component.</span>
The Force need to accelerate the object is by 3 m/s² is 15 N. Suppose a friction force of 5 N acts on the motion of the object, the force needed to be applied to the object is 20 N
<h3>Force:</h3>
This can be defined as the product of the mass and the acceleration of a body. The S.I unit of force is kgm/s or Newton(N)
To calculate the force needed to accelerate a mass of 5 kg object at 3 m/s² we use the formula below.
Formula:
- F = ma........ equation 1
Where:
- F = Net force needed to accelerate the object
- m = mass of the object
- a = acceleration of the object
From the question,
Given:
Substitute these values into equation 1
Suppose a frictional force of 5 N acts on the motion, The force applied is
- F = F'+ma............ Equation 2
Where:
- F = Frictional force = 5N
Substitute into equation 2
- F = 5(3)+5
- F' = 15+5
- F = 20 N.
Hence, The Force need to accelerate the object is by 3 m/s² is 15 N. Suppose a friction force of 5 N acts on the motion of the object, the force needed to be applied to the object is 20 N
