Answer:
Velocity (magnitude) is 98.37 m/s
Explanation:
We use the vertical component of the initial velocity, which is:
Using kinematics expression of vertical velocity (in y direction) for an accelerated motion (constant acceleration, which is gravity):
Now we need to find 
as a function of 
. We use the horizontal velocity, which is always the same as follow:
We know the angle at 3 seconds:
Substitute 
in 
and then solve for
With this expression we go back to the kinematic equation and solve it for initial speed
Answer:
A balance
Explanation:
Scientists measure mass with a balance, such as a triple beam balance or electronic balance. In science, the volume of a liquid might be measured with a graduated cylinder.
We have that the value for y is
From the Question we are told that
Relaxed length of 35 cm (0.35 m)
Spring stiffness is 12 N/m.
Glue a 66 gram block (0.066 kg)
Total length is l_t=16 cm
Block during a 0.24-second interval
Generally the equation for the Force of spring of block is mathematically given as
Generally
Generally,Net Force
Generally,Velocity of block
Where
Therefore
Generally the equation for the Velocity of block is mathematically given as
