The acceleration formula goes like this: a= (vf-vi)/t so it would be (13-4)/3 Thus the answer is 3m/s^2
Answer:
Explanation:
The two triangles are similar what is the length of DE
Answer:
motion energy
Explanation:
motion wnergy is the sum of potential and kinetic energy
Answer:
Explanation:
We know that the pressure can be calculated in the following way:
p = d·g·h
with d being the density of the water, g the gravitational acceleration and h the depth.
Also d of the water = 1000 kg/m^3 circa and g = 9.8 m/s^2 circa
117,500 Pa = 1000kg/m³ · 9.8m/s² · h
Therefore h = 11,9 m
The minimum is 3 Newton, when the two forces act in opposite directions.
