Answer:
20 A
Explanation:
Given
Spring pulled from position
x = 5A
we need to calculate total distance of one full cycle of spring motion
if you see image below, you understand easily
When cycle complete
Its total distance become 20 A

Answer:
The velocity of the student has after throwing the book is 0.0345 m/s.
Explanation:
Given that,
Mass of book =1.25 kg
Combined mass = 112 kg
Velocity of book = 3.61 m/s
Angle = 31°
We need to calculate the magnitude of the velocity of the student has after throwing the book
Using conservation of momentum along horizontal direction
Put the value into the formula
Hence, The velocity of the student has after throwing the book is 0.0345 m/s.
