A bus is moving with an acceleration of 4 m/s^2. If it was initially at rest, what will be its speed at the end of 2 seconds? *

a) 8 m/s
b) 6 m/s
c) 2 m/s
d) 0.5 m/s

Which lists the pairs of plates in order from least to greatest in terms of the work done to move the electron?

Dao makes a table to identify the variables used in the equations for centripetal acceleration. what quantities belong in cells x and y?

Aleaky 10-kg bucket is lifted from the ground to a height of 15 m at a constant speed with a rope that weighs 0.7 kg/m. initially the bucket contains 45 kg of water, but the water leaks at a constant rate and finishes draining just as the bucket reaches the 15-m level. find the work done. (use 9.8 m/s2 for g.) show how to approximate the required work by a riemann sum. (let x be the height in meters above the ground. enter xi* as xi.) lim n → ∞ n (9.8)(45−3 xi) i = 1 δx express the work as an integral. 0 dx evaluate the integral. (round your answer to the nearest integer.) j
