The spleen is the mains structure of the lymphatic system!
Humans population had dropped by half since the 1960s from 2.2% in 1962 to 1.15% today
Answer:
4.80 m
Explanation:
We are given the mass of the high jumper, its initial velocity, and the acceleration of gravity. We are trying to find the vertical displacement of the high jumper.
Let's set the upwards direction to be positive and the downwards direction to be negative.
List out the relevant known variables.
- v₀ = 9.7 m/s
- a = -9.8 m/s²
- Δx = ?
We still need one more variable in order to use the constant acceleration equations. Since we are trying to find the max height of the jumper, we can use the fact that at the top of its trajectory, its final velocity will be 0 m/s.
4. v = 0 m/s
Using these four variables, let's find the constant acceleration equation that contains these variables:
Substitute the known values into the equation and solve for Δx.
- (0)² = (9.7)² + 2(-9.8)Δx
- 0 = 94.09 + (-19.6)Δx
- -94.09 = -19.6Δx
- Δx = 4.80
The high jumper can jump to a max height of 4.80 m.
Answer:
Here gravitational force is G or gravity constant.
Answer:
deceleration is the opposite of acceleration
Explanation:
We know that acceleration is the increase of speed with respect to time. So deceleration must be represented on the graph as a decrease in speed over time.a
is the permeability of free space.
