If t is time, v velocity and a acceleration, then the dimension of t2va is Group of answer choices T2L2 LT2 L2T T2/L2 L2/T
suppose the x-velocity vx of the car at any time t is given by the equation: vx=10m/s + (1.50m/s) t*square* a) find the average x-acceleration in the time interval t1= 1 s and t2= 2.5 s b) derive an expression for the instantaneous acceleration as a function of time, and use it to find ax at t=1 s and t=2.5 s
13. What is the instantaneous velocity and instantaneous speed at t 4? 14. For what time interval(s) is the velocity (a) negative? (b) positive? (c) zero?
Please show all your work.
5) Acceleration is to velocity as velocity is to position . aaux"# r where vr įs the instantaneous velocity. So the average acceleration is about how rapidly the instantaneous velocity is changing, and the sign tells about the direction of the change. At For the pendulum, you made estimates of the instantaneous velocity for ←2.05[s] and t= 2.5%]. Also, the average speed and average velocity estimates that you made at other times may be reasonable...

Write an expression for the instantaneous voltage V(t) delivered by an ac generator supplying 120 V rms at 60 Hz. Assume the voltage is 0 at time t = 0, and leave the factors in exact form; do not round their values, write the argument of the sinusoidal function to have units of radians, but omit the units.

A car’s position as a function of time is given by the following equation: x(t) = 5 m/s t + 2.8 m/s2t2– 0.15 m/s3t3. Find the average velocity from 0 to 5 s. Find the instantaneous velocity at 0, 3, and 5 s. Find the average acceleration from 0 to 5 s. Find the instantaneous acceleration at 0, 3, and 5 s. At what POSITIVE time does the car come to rest?
1. An object with an initial velocity to right immediately has a negative acceleration for t seconds a) Draw a velocity vs. time graph b) State what the slope of velocity vs. time graph says about the motion of the object c) Create an equation for the area between the velocity curve and the time axis in terms of the initial velocity, the change in velocity, and the change in time
