Question
I just need help understanding how to calculate the highlighted blocks' information. I have uploaded the pre-lab as well for reference.
Pre-Lab Questions In one of your experiments, you will roll a marble down a ramp to provide an initial horizontal velocity. Suppose you start the marble at rest (u 0 m/s) and it travels a distance.of.d, down the ramp. Use 1-D kinematics to predict the velocity of the ball (u at the bottom of the ramp. Hint; the acceleration of the ball down the ramp is 9.81 sin(e) m/s2 where 0 is the angle of the ramp. Record you answer in variables (you will calculate the velocity with magnitudes when you perform the experiment) 1. VV19.62sine S Use the kinematic equations to derive a general equation for the time it takes a ball dropped from rest at vertical height, h, to reach the ground. 2. 2h Use the result from Question 2 to write a general equation for the distance travelled by a projectile that is rolling of a table of height, h, with a horizontal speed, vox 3. 4. The range of projectiles is dependent on the velocity and angle of the launch. Use the kinematic equations R-vsin(20) to show the range of a projectile launched at velocity, v, and angle, e, is equal to Hint: The velocity at the beginning and end of the motion has the same magnitude, but opposite direction u2 * 2 * sine * cosExplanation / Answer
You need to perform the experiment in the laboratory with various sets of ramp distance (d ), angle of ramp (theta), and other parameters. The formula given in questions are used to calculate theoretically what should be your velocity and range. The range you calculate from formula is the predicted range. And the range you obtain by performing the experiment with a particular set of angle as well as distance of ramp will give you the actual range.. the average actual range can be calculated if you perform the experiment with same value of angle and distance of ramp for two or more different times in order to ensure accuracy of your experiment.
