Answer:
spring constant of the spring is 1820.44 N/m
Explanation:
given data
ball mass = 4 kg
speed = 16 m/s
distance = 0.75 m
to find out
spring constant of the spring
solution
we know that kinetic energy of ball = energy store in spring as compression
so we can express it as
0.5 × m × v² = 0.5 × k × x² ....................1
so put here value we get spring constant k
m × v² = k × x²
4 × 16² = k × 0.75²
solve it we get
k = 1820.44 N/m
so spring constant of the spring is 1820.44 N/m

The total resistance is the reciprocal of (1/7+1/5+1/4+1/2) = 0.915 ohm. The battery voltage makes no difference. It would be 0.915 ohm even if the resistors were connected in parallel and just laying in the drawer.
Answer:
the magnitude of A is 3.577
Explanation:
According to the question it is given that there is a magnitude of 8.0 m that added to the vector A that lies on x axis also the sum of two vectors would be third vector by considering the y axis and the magnitude is the twice of the magnitude B
The computation of the magnitude of A is shown below:
A = 3.577
Hence, the magnitude of A is 3.577
