160j of work was needed in order to move an object 8m acroos a
floor what was the force in N that was needed to do this job? i
think it may be not sure but 20N dont agree with me just maybe your
imput will be different

There is a formula to calculate the speed of a car after
accelerating for four seconds. This formula is v = u + at, where v
= velocity, u = initial velocity, a = acceleration, and t = the
time it takes to accelerate.
