Answer:
(a) = 3910
(b) = 5181
(c) = 2762955 m
Explanation:
Using equations of uniformly accelerated motion:
Equations:
-
-
(a) Using equation 1:
⇒ Because it upward from rest
(b) Using equation 1:
⇒ Because is the is the initial speed in the movement before changing acceleration
(c) Using equation 2:
⇒ and Because it upward from rest
⇒
Explanation:
We use Hooke's Law, which states that,
F=kx
F- is the force in newtons
k- is the spring constant
x- is the extension of the spring in meters
Solving for k we get k=F/x
k= 10N/0.50m
=100 N/m
Answer:
Impulse-The effect of force acting over time to change the momentum of an object.
momentum-The product of mass of a particle and its velocity.
it would be arrows that all align in one direction.
