A 89-kg fullback is running at 3.5 m/s to the east and is stopped in 0.85 s by a head-on tackle by a tackler running due west. Required:
a. Calculate the original momentum of the fullback.
b. The impulse exerted on the fullback.
c. The impulse exerted on the tackler
d. The average force exerted on the tackler.

Fitness is the ability to perform only very light levels of physical activity.

How are period and frequency related to each other? dperiod is the reciprocal of frequency.

Since you have not included the experiment situation and the data, of course, i can not give you specific details about it. but i can you with this question.1) i will assume that the motion is projectile (parabolic) motion.2) yes, the horizontal distance depends on the horizontal velocity as, naming vx the horizontal velocity and t the time, it is: x = vx × t3) now, observe that the flight time depends on the vertical velocity as, naming voy the initial vertical velocity, t the time and y the vertical distance before reaching the ground: y = yo + voy×t - gt² / 2.the higher the initial vertical velocity (voy) the longer the object will be flying and so t will be higher in the equation for the horizontal distance.that explains the relationship between the horizontal distance and the horizontal velocity.

What are your choices. i believe it might be mitochondria but i will know for sure when i see the choices. let me know okay i'm happy to answer
