If not, explain why you disagree and calculate the initial speed vo of the block. A simple pendulum consists of a particle of mass m suspended by a long, massless wire of length L. (Note: Neglect all frictional effects.) Draw a free-body diagram for the pendulum bob corresponding to a moment when the bob is located an angular displacement away ...

3 Ways to Calculate Speed - wikiHow
What is the acceleration of an object that takes 20 sec to change from a speed of 200 m/s to 300 m/s? Formula: Acc= Final speed- Initial speed/time 300m/s-200m/s. Acc = 20sec = 5 m/s2. A car traveling south at a velocity of 30 m/sec slows down to a velocity of 10 m/sec in 10 sec. Calculate the deceleration.

Part 1: Finding the projectiles initial speed. To find the projectiles initial speed you may choose a few different methods. The easiest would be through an energy analysis where you can calculate the speed of the box and projectile upon impact: (KE = F x d. or. ½MVf2 – ½MVI2 = Fk x d. Where Vf = 0 and Vi = the initial velocity of both the ...

You could then calculate the speed of sound using . Although this would work, it is not very practical and is subject to random errors due to reaction time and interference from other sounds. To use an echo to measure the speed of sound over short distances in the lab we need a more precise timing system.
