Try to put rb.Sleep () before spawning and also set rb.angularVelocity and rb.velocity to 0. When done with all other code put rb.WakeUp (). WebModified 6 years, 10 months ago. Viewed 1k times. 1. Given trajectory s ( t) = 2 t 3 − 15 t 2 + 36 t + 2 find, when velocity v = 0. I'm doing this the following way: v = d s d t = 6 t 2 − 30 t + 36. Then making v = 0, i.e. 6 t 2 − 30 t + 36 = 0 and solving that equation we get t 1 = 2 and t 2 = 3. I am right?

WebThe initial angular velocity of the door is zero. The students conduct the experiment and gather data about the net torque exerted on the door and angular acceleration of the door for several trials. They create a graph of the door's angular acceleration as a function of the net torque and sketch a best-fit line through the data. WebAnswer (1 of 2): The point at which a fluid particle is bruoght to rest ISENTROPICALLY is called as stagnation point. Means the fluid particle is brought to rest without any change in entropy.
