Please see the explanation below

#"Part A"#

Apply the equation of motion

#v=u+at#

The constant speed is

#v=0+1.95*18.4=35.88ms^-1#

#"Part B"#

If the speed is constant, the acceleration is #=0ms^-2#

#a=0ms^-2#

#"Part C"#

Apply the equation of motion

#v=u+at#

#t=(v-u)/a=(0-35.88)/(-3.539)=10.14s#

#"Part D"#

The total distance travelled is the area under the velocity-time curve

#d_( t o t)=(1/2*35.88*18.4)+(35.88*68.2)+(1/2*35.88*10.14)#

#=330.1+2447.0+181.9#

#=2959m#
