Answer:
Explanation:
initial frequency of revolution is given as
now initial angular speed is
Similarly final angular speed is given as
Now angular acceleration is given as
The pressure is the force divided by the area to which the force is applied, so in this problem it is equal to:
Answer:
A. TRUE
B. TRUE
C. It depends on the mass of both the objects
D. TRUE
Answer:
Vmax=11.53 m/s
Explanation:
from conservation of energy
Spring potential energy =potential energy due to elevation
0.5*k*x²= mg=mgh
0.5*k*2.3²= 430*9.81*6
k=9568.92 N/m
For safety reason
k"=1.13 *k= 1.13*9568.92
k"=10812.88 N/m
agsin from conservation of energy
spring potential energy=change in kinetic energy
0.5*k"*x²=0.5*m*
10812.88 *2.3²=430*
=11.53 m/s
