Answer:
The mass of the receiver is 85 kg.
Explanation:
Given:
Mass of the tackler (M) = 130 kg
Mass of the receiver = 'm' (Assume)
Initial velocity of the receiver (u) = 0 m/s
Initial velocity of the tackler (U) = 3.8 m/s
Final combined velocity (v) = 2.3 m/s
So, as per question, the momentum is conserved. Therefore, the total initial momentum is equal to the total final momentum.
Total initial momentum is given as:
Total final momentum is given as:
Now, as per momentum conservation:
Therefore, the mass of the receiver is 85 kg.
Answer:
a = 2.5 [m/s²]
Explanation:
To solve this problem we must use the following equation of kinematics.
where:
Vf = final velocity = 25 [m/s]
Vo = initial velocity = 0 (star from the rest)
a = acceleration [m/s²]
t = time = 10 [s]
25 = 0 + (a*10)
a = 25/10
a = 2.5 [m/s²]

Answer:
Ribosomes: Produce proteins by following coded instructions that come from DNA.
Endoplasmic reticulum: Where lipids, including those needed for the cell membrane, are synthesized, along with proteins and other materials that are exported from the cell.
Vesicles: Store and move materials between cell organelles, as well as to and from the cell surface.
Golgi apparatus: Modifies, sorts, and packages proteins and other materials from the endoplasmic reticulum for storage in the cell or release from the cell.
