Answer:
3 m/s^2
Explanation:
avg. acceleration= (change velocity)/ time
[v(final)-v(initial)]/(t2-t1)
[(300 m/s)-(0 m/s)]/(100s-0)
(300 m/s)/(100s)
= 3 m/s^2
Answer:
each cement block supports a 2n force
Explanation:
<span>You can prove that moon is in motion by taking two photos with the following features:
They are taken at the same hour and minute.
They are taken on two different nights.
They are taken from the same location.
This would allow an accurate comparison and would should the moon's motion.
I hope this helped! :)</span>
Answer:
2.1 m/ss
Explanation:F=ma a=F/M a=4,200/2,000= a=2.1 m/ss
Answer:
Explanation:
Newton’s second law states that the acceleration a of an object is proportional to the force F acting on it is inversely proportional to its mass m. The mathematical expression for the second law of motion is given by :
F = m × a
F is the applied force
m is the mass of the object
a is the acceleration due to gravity
We need to find the dimensions of force. The dimension of force m and a are as follows :
So, the dimension of force F is, . Hence, this is the required solution.
