Use the data in the image to calculate Mara’s average speed in meters/per second after 25 m.

Dis the

F= (mass)(acceleration) = mam = 0.25 kgvi = 16 m/st = 2 svf = 0 m/s (since it was put to stop)a=(vf-vi)/ta=(0-16)/2a = 8 m/s^2 (decelerating)f = ma = (0.25 kg)(8 m/s^2)f = 2 nhope this !

Iwas thinking the wavelength is one half its original value
