Thank you for the opportunity to help you with your question!
Given v^2=2gy ....(1)
Differentiating this above equation with respect to v, we then have
Dividing both sides with v^2, we have
Grom equation (1), we have
Given that dy/y=0.05 and dv/v=0.0413
Substituting this in equation(2), we have
the percent uncertainty in the calculated value of g is 3.26%
Thank you, Could you also help me with this one?
A small block travels up a frictionless incline that is at an angle of 30.0° above the horizontal. The block has speed 4.21 m/s at the bottom of the incline. Assume
acceleration on the frictionless incline a==-gsin(30)=-g/2
initial velocty=u=4.21 m/s
Using kinematics equation, v^2=u^2-2aS
S is the distance travelled by the block.
as v=0, u^2=2aS
