Determine the acceleration of a boat with a final speed of 120 m/s after 30 seconds The boat accelerates at a rate of __ m/s2

f=ma newton

f=100x2.5=250n

conservation of mass

mass before something happens = mass afterwards

the tires are rotating at 0.434 rpmlinear speed=45 m/sdiameter=0.550 mradius=0.275 mnow v= rωω= v/rω=45/0.275ω=163.6 rad/sω=163.6 rad/s (1rev/2π rad) (60s/1m)ω=1563 rpm

the answer should be in the picture.
