I am working on finding the inital velocity of a class II projectile and am having trouble determining the right amount of sig figs.
The taken measurements of the initial position of x goes to 4 sig figs, as well as the final position for y.
With that being said, I am trying to find the initial velocity of x and y separately through trionometry. For example, if I have an equation for the initial velocity of x with an angle of 40, then
Vox=Vocos40
My question is, since the measured value for my angle is two significant figures, is my answer Vox=.76Vo also in two sig figs because it goes by the two significant figures from my measured angle, or should I go to four significant figures to match my measured values for x and y?
A projectile is fired from 3 meters height above level ground with an initial velocityequals to 20 m/s and at an angle equals to 30 degrees above the horizontal level. Notethat the air resistance is neglected.
the position of a particle with respect to time is defined by:r(t) = rcos(cot )i +rsin(cot)j ,where w and r are constants.Demonstrate that the magnitude of the acceleration of the particle is constant.
Consider a projectile fired with an initial velocity perpendicular to
an incline sloping downward at an angle α with respect to the horizontal. When it eventually
lands on the incline, let its velocity make an angle θ with respect to the horizontal. Obtain the
(a) angle θ, (b) the value of α that yields the minimum value of θ, and (c) the corresponding value
of this minimum θ. (d) If a rock is thrown at the top of the same incline, what angle θ from the
horizontal should rock be thrown so that it has the greatest range?
