Answer:
a) The velocity is 2.94m/s
b) 0.441
Explanation:
a) Assume gravity is 9.8m/s^2
Use the equation below to solve for the velocity at 0.30 seconds
,
vf =unknown velocity vi= initial velocity vi=0m/s a= 9.8m/s^2 t=0.30seconds
Step 1: Substitute the variables with the knowns
Step 2: Solve
b)
Use the equation below to solve for the displacement at 0.30 seconds
Step 1: Substitute the same variables with the knowns
Note that vi*t=0 as vi=0m/s
Step 2: Solve
x=0.441m
Answer:
A.
Explanation:
If its at a height the Gratitude of it falling down with only Gravity if Any other Forces are acting on it so as Friction But Sideways.
Answer:
Part a)
Final speed of the corn is 19.05 m/s
Part b)
Kinetic energy of the corn is 3.1 J
Explanation:
Part a)
As we know that the initial position of the corn is
h = 18.5 m
now we also know that it will fall from rest and moving under constant acceleration so we will have
Part b)
Kinetic energy of the corn is given as
Answer:Mechanical waves, electromagnetic waves, and matter waves.
Explanation: does are the waves
