If an object that was held steady (0 speed) and then dropped, how many meters would it fall in one second?

When the force acting on an object points at least partially in the direction of the motion the work done is considered to be negative

14. a body is projected with velocity vi from a.at the same time another body is projectedvertically upwards from point b withvelocity v2 lies vertically below the highestpoint. both the bodies collide thenv2÷v1is

Vi. on another planet, a spring with constant 4.7 n/m is set up and allowed to expand verticaly freely. 8.4kg mass is placed on the spring and the spring extends 5.28m. calculate the exected extension on earth.
