Question

Pls answer I am very angry now nobody is helping me why is brainliest for send 5 times a question is there any physics expert pl solve

Answer 1

a) accelaration = v-u/t = 10-0/10 = 1m/s^2
retardation = 1m/s^2 ( from t 30s to 40s) or accelaration = -1m/s^2 ( since retardation is negative accelaration)

b)Distance travelled from t 0s to 30s = area of trapezium = sum of parallel sides × height = (30+10)×10 = 400 m

c) OE = uniform accelerated motion
ED = constant speed
DC = uniform retarded motion


Hope this helps!!!
If it does, plz mark as brainliest

Answer 2

ans of 3rd question :

OE= uniform accelerated motion

ED=uniform linear motion

DC=uniform retardated motion
