answers A. 0.5m per second square and b. retarding F =500N
Explanation:
Given that
Mass =1000kg
Speed = 10m per second
Distance = 100 m
To find
a. Retardation or acceleration
b. Retarding Force
A. S =ut+1/2at^
100=0×10 +1/2 × a ×10^
100=0+1/2×a×100
100=50a
a=50/100
a=0.5m/s^
b. F = mass × acceleration
F=1000×0.5
F=500N
