Answer:
Maximum height will be
Explanation:
We have given initial velocity through which basketball is thrown
Acceleration due to gravity
At maximum height velocity will be zero
So final velocity v = 0 m /sec
According to third equation of motion
( Negative sign is due to upward acceleration )
Answer:
v = 0
Explanation:
This problem can be solved by taking into account:
- The equation for the calculation of the period in a spring-masss system
( 1 )
- The equation for the velocity of a simple harmonic motion
( 2 )
where m is the mass of the block, k is the spring constant, A is the amplitude (in this case A = 14 cm) and v is the velocity of the block
Hence
and by reeplacing it in ( 2 ):
In this case for 0.9 s the velocity is zero, that is, the block is in a position with the max displacement from the equilibrium.
