Question

please help me to do the answer of physics of chapter motion?​

Answer 1

Answer:

hey mate here is ur ns

Explanation:

given, u = 90km/hr = 90×5/18 = 25m/s

v= 0 m/s (rest)

a= -0.5m/s²(retardation)

a = v-u/t

-0.5 = 0-25/t

t = 25/0.5 = 50s

s = ut+1/2at²

s = 25(50)+1/2(0.5)(50)² (in that case acc

= 1250+1250 will be +ve b/c

= 2500 m. distance can't be

hope it help u. -ve or zero )
