I really need help with this question. I've tried solving it but i just can't do it.
The question
A loaded dump-truck having a total mass of 2.4*10power of 4 kg is traveling east at 85km/h.The truck driver can apply a braking force of 5.5*10 power of 4 to the wheels without causing the wheels to lock and skid. Calulate:
A)the maxium negative acceleration of this trunk.(in m/s2)
B)the minimum stopping time
C)the minimum stopping distance
The only thing I know is the mass. I know you are supposed to use the 85km/h for something I can not figure out for what.
Thanks
