Answer:
1.944m_s²
Explanation:
First convert speed from km/h to m/s the use the formula a=v-u
t
Answer:
0.99Hz
Explanation:
Using F= -mx ( spring force)
At equilibrium the gravitational force will be balanced by the spring force so mg= kx
K= mg/ 0.25 N/m
But
Frequency f= 1/2pi √g/0.25
Frequency is 0.99Hz
Because the coefficient of friction depends on the surface
Answer:
the second one Test the rate of decay of specific elements in rock samples.
