On Earth, a cannonball with a mass of 20 kg would weigh 196 Newtons.
With the formula F=mg, where F is the weight in Newtons, m is the mass, and g is the acceleration due to gravity on the Earth which is 9.8m/s^2.
F=20kg x 9.8m/s^2= 196 Newtons
BUT on the moon, acceleration due to gravity is 1.6 m/s^2,
so F=mg=20kgx1.6m/s^2= 32 N
I found the answer for you if u need any help ask anytime!
Acceleration = (change in speed) / (time for the change) = 9/3 = <em>3 m/s²</em> .
His mass makes no difference.
Answer:
Acceleration=
Speed=0.67 m/s
Explanation:
We are given that
Horizontal force=F=20 N
Mass of box=m=40 kg
We know that
Acceleration=
Using the formula
Acceleration of box=
The acceleration of the box=
Initial velocity=u=0
Force=F=30 N
Distance=s=0.3 m


Substitute the values



Hence, the speed of the box after it has been pulled a distance of 0.3 m=0.67 m/s
