Explanation:
This equation for acceleration can be used to calculate the acceleration of an object that is acted on by a net force. For example, Xander and his scooter have a total mass of 50 kilograms. Assume that the net force acting on Xander and the scooter is 25 Newtons. What is his acceleration? Substitute the relevant values into the equation for acceleration:
<h2>Answer:</h2>
a=Fm=25 N50 kg=0.5 Nkg
The Newton is the SI unit for force. It is defined as the force needed to cause a 1-kilogram mass to accelerate at 1 m/s2. Therefore, force can also be expressed in the unit kg • m/s2. This way of expressing force can be substituted for Newtons in Xander’s acceleration so the answer is expressed in the SI unit for acceleration, which is m/s2:
a=0.5 Nkg=0.5 kg⋅m/s2kg=0.5 m/s2
The car would go from zero to 58.0 mph in 2.6 sec.
Since the force on the car is constant, therefore the acceleration of the car would also be constant.
Now for constant acceleration we can use the equation of motion
Using first equation of motion to calculate the acceleration of the car
v=u+at
29=0+a×1.30 ...... Eq. (1)
Again using the first equation of motion
58=0+a*t ....... Eq. (2)
Dividing eq. (2) with equation 1
t=2×1.3
t=2.6 sec
Answer:
Newton's law of gravitation states that every object in this universe attracts every other object with a force called gravity,
when the distance between the two object is increased the gravitational force decreases by its square,
and when the mass an object increases the gravitational force also increases,
therefore, gravitational force is directly proportional to the mass of the two objects and is square inversely proportional to distance between them.
Hope it helped u,
pls mark as the brainliest and put thanks

Answer:
Water
Explanation:
windmills were used to bring water to farms in ancient times.
Force=mass x acceleration. F=1kg x 2m/s^2.
F=2 Newtons
