A sports car that can accelerate at the rate pf 5.7 m/s^2 drag races agains a speedster that can accelerate at the rate of 4.53 m/s^2. the speedster gets a 1.41second head start.
Sports car acceleration:5.7 m/s^2
speedsters acceleration:4.53 m/s^2
how do i find the time it takes for the...
if you drop on object, it will accelerate downward at a rate of g=9.8m/s^2
if you throw it downward instead, it's accerleration (absence of air resistance) will be :confused:
a) greater than 9.8 m/s^2
b) unable to determine
c) 9.8 m/s^2
d) less than 9.8 m/s^2
Sphere 1 has surface area A1 and volume V1, and shere 2 has surface area A2 and volume V2.
If the radius of shere 2 is four times the radius of shere 1, what is the ratio A2/A1 of the areas?
