Its acceleration is constant.
It is beacuse of fluid If there is no fluid, there is no drag. Drag is generated by the difference in velocity between the solid object and the fluid. If this statement is correct then how can there be drag in space if there is no air?
Answer:
0.5 V
Explanation:
The electric potential distance between different locations in an electric field area is unaffected by the charge that is transferred between them. It is solely dependent on the distance. Thus, for two electrons pushed together at the same distance into the same field, the electric potential will remain at 1 V. However, the electric potential of one of the two electrons will be half the value of the electric potential for the two electrons.
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
