A car is speeding at miles per hour. How many meters per minute is the vehicle travelling?

OpenStudy (anonymous):

70 miles per hour

OpenStudy (anonymous):

1 mile = 1.609344 kilometers so convert 70 miles to kms using this value to get kms / hour multiply by 1000 to get meters to hour then divide by number of seconds in an hour to get meters / second

ok i got it. do you think you can help me with this one? At a certain altitude and time, a rocket's acceleration is . One gravity (g) is equivalent to . What is the rocket's acceleration in meters per square second?

OpenStudy (anonymous):

oh - you need meters per minute so the last sentence should by divide by 60

At a certain altitude and time, a rocket's acceleration is 3.75g . One gravity (g) is equivalent to 32.2ft/s^2 . What is the rocket's acceleration in meters per square second?

OpenStudy (anonymous):

3.75(32.2ft/s^2)*(1m/3.28ft)

OpenStudy (anonymous):

conversion factor for ft to meters is 1ft = .3048 meter 32.2 ft /s^2 = 32.2 * 0.3048 m/s^2 required acceleration is 3.75*32.2 * 0.3048 m/s^2
