suppose a spring of angular frequency 8.08 s" is compressed 0.100 m from
(10 = -0.100 m) but is given a shove to create a velocity in the +x direction of vo = 0.400 m/s
(a) the phase angle , (b) the amplitude a, and, (c) the displacement x as a function of time,
20.

the speed of the cart after 3 seconds of low fan speed is ⇒ 54.0 cm/s.

the speed of the cart after 5 seconds of medium fan speed is ⇒ 120.0 cm/s.

the speed of the cart after 2 seconds of high fan speed is ⇒ 64.0 cm/s. 

just did the lab.

I'm having some difficulty seeing the diagram clearly.but the question says there's a net inward force on the object.so we know right away,  from newton's 2nd law of motion, thatthat baby is accelerating.  it doesn't even matter which way thenet force is pointing.  if there's any net force, then either theobject's speed or else its direction must be changing.

Answer is trees if this doesnt try using google
