Two forces act on a 2.2 kg particle. The first force is applied with magnitude 7.18 N at 69.7 degrees below the +x axis. The second force is applied with magnitude 3.12 N at 37.0 degrees above the +x axis. Determine the magnitude of the particle's acceleration.

Which quantities are scalars? choose all that apply a.distance b.speed c. acceleration d.velocity

The act of moving from one place to another. a. locomotor b. aerobic c. stationary d. static

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
