Surfing For A Car Moving At 50 Km H?

Thomas asks…help physics questions. 10 points for best answers?1. a car is moving at 60 km/h when it begins to slow down with a declaration of 1.50 m/s/s. how long does it take to travel 70 m as it slow down

2. A car starts from rest accelerates constantly to 50m/s for 100m. calculate:
time taken for the acceleration?
Acceleration and velocity at the third second?

pleaseeeeee explain to mee, thxNancy answers:First convert 60km/h to m/s
60/3.6= 16.666m/s
then use s=ut+1/2at^2 reaaranged for
