A Dodge Viper can go from 0 to 60 mph (27 m/s) in 3 seconds. What is its average acceleration in m/s^2 during that take off? ANSWER WITH A SINGLE WHOLE NUMBER.

The Kinda Ka roller coaster in Jackson, New Jersey is the U.S. roller coaster with the highest top speed: 128 mph or 57.2 m/s. Suppose it accelerates from 20 m/s to its top speed in 0.75 seconds. What would be its average acceleration in m/s^2 during that time? Round to the nearest tenth and ANSWER WITH JUST A NUMBER (containing a decimal point).

What single letter abbreviates the standard acceleration due to gravity on earth?

What is g in m/s^2? Round to the nearest HUNDREDTH and ANSWER WITH JUST A NUMBER (containing a decimal point).

What is 6g in m/s^2? (Recall: g = 9.81 m/s^2) Round to the nearest tenth and ANSWER WITH JUST A NUMBER (containing a decimal point).

The Tower of Terror in Johannesburg, South Africa holds the record for fastest accelerating roller coaster, at 61.8 m/s^2. How many g's is that? (Recall: g = 9.81 m/s^2) Round to the nearest tenth and ANSWER WITH JUST A NUMBER (containing a decimal point).
