It has three significant figure
Yes. It means that the acceleration increases at a constant rate, for example 3 mph every second.
Answer:
thick wire and cold temperatures
Answer:
Explanation:
a = 4ms⁻², Vf = 180 m/s & Vi = 140m/s
a =
4 = 
t = 40/4
t = 10sec
To Measure Distance Use third Equation of Motion:
2aS = Vf²-Vi²
S = 
S = 12800/8 = 1600m
