A student standing on a dock observes a piece of wood floating on the water as shown below. The wavelength of the wave is: *
2m and 2m

less than one you can't create energy

answergravity;

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.

you get 2.3=1.21*\frac{a}2 or 4.6=1.21a or a=3.802 (b)
