An astronaut is on a new planet. She discovers that if she drops a space rock from 19.22 m above the ground, it has a final velocity 7.09 m/s of just before it strikes the planet's surface. What is the acceleration due to gravity on the planet? Answer in 2 decimals
. A Tesla can accelerate from 0-60 MPH in 2.8 seconds, yielding an average acceleration of 21.4 MPH/s. c. Convert this acceleration into m/s (meters/sec3). d. If 1.0 furlong = 660 ft and 1.0 fortnight = 2 weeks, convert this acceleration into furlongs/fortnight squared. %3D
Acceleration is sometimes expressed in multiples of g, where g = 9.8 m/s2 is the magnitude of acceleration due to the earth's gravity. In a test crash, a car's velocity goes from 26 m/s to 0 m/s in 0.15 s. How many g's would be experienced by a driver under the same conditions?
you drop a ball from a height of 2.00 m above the floor. The ball hits the floor 0.319 s after your drop it. You guess that you must have been taken to an alien planet with gravity different from Earth s. What is this planet s g (that is, the magnitude of the acceleration due to gravity on this planet)? 29.5 m/s^2 59.0 m/s^2 39.3 m/s^2 19.7 m/s^2

A cannon ball is launched into the air with an upward velocity of 336 feet per second, from a 14-foot tall cannon. The height hh of the cannon ball after tt seconds can be found using the equation h=−16t2+336t+14h=-16t2+336t+14. A) What was the initial height of the cannon ball? feet B) How many seconds will it take for the cannon ball to hit the ground? seconds {Round to 3 decimal place.}
While playing sock baseball in the living room, a child swings a pair of socks attached to the end of a string in a circular path above his head. If the socks travel at a constant speed of 3.7 m/s and the string is 0.4 m long, what is the acceleration (in m/s2) experienced by the socks?
