There is a clever kitchen gadget for drying lettuce leaves afteryou wash them. it consists of a cylindrical container mounted sothat it can be rotated about its axis by turning a hand crank. theouter wall of the cylinder is perforated with small holes. you putthe wet leaves in the container and turn the crank to spin off thewater. the radius of the container is 12 cm. when the cylinder isrotating at 2 revolutions per second, what is the magnitude of thecentripetal acceleration at the outer wall?
a. 4.8 m/s2
b. 19 m/s2
c. 27 m/s2
d. 9.8 m/s2
e. 6.0 m/s2

Afaulty model rocket moves in the xy-plane (the positive y direction is vertically upward). the rocket's acceleration has components ax(t) = ? t2 and ay(t) = ? ? ? t, where ? = 2.50 m/s4 , ? = 9.00 m/s2 , and ? = 1.40 m/s3 . at t = 0 the rocket is at the origin and has velocity ~v0 = v0x ? i + v0y ? j with v0x = 1.00 m/s and v0y = 7.00 m/s. (a) calculate the velocity and position vectors as functions of time. (b) what is the maximum height reached by the rocket? (c) sketch the path of the rocket. (d) what is the horizontal displacement of the rocket when it returns to y = 0?
