Answer: Get stronger. Strength is critical to running fast because the more force you can exert against the ground the faster you can run.
Apply your new strength. Being strong is important for sprinting, but the ability to apply it is even more important. Sprinters move in a horizontal direction.
Take longer steps more quickly. Today, the concept of exerting more force against the ground is very popular for improving speed. ...
Run fast to get fast. Of all the strategies described in this article, this is the most important and often the most overlooked.
Explanation:
Answer: B to C
Explanation: The line is curving inwards, practically calculating the stance that it had went down. If it went straight across, it stayed the same till a specific point, furthermore calculating the bent line bending upwards is actually a partial-raise, conclude points B to C is most likely an un-even balance, meaning it had went down; or decreasing. B to C is the decreasing segment of this equation/problem (question).
C) above, the Earth's core is about the melting point of iron.
Mass have no effect for the projectile motion and u want to know the height "h"
first,
find the vertical and horizontal components of velocity
vertical component of velocity = 12 sin 61
horizontal component of velocity = 12 cos 61
now for the vertical motion ;
S = ut + (1/2) at^2
where
s = h
u = initial vertical component of velocity
t = 0.473 s
a = gravitational deceleration (-g) = -9.8 m/s^2
h=[12×sin 610×0.473]+[−9.8×(0.473)2]
u can simplify this and u will get the answer
h=.5Gt2
H=1.09m
