160j of work was needed in order to move an object 8m across a floor what was the force in N that was needed to do this job
Definition1/7

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

If a graph shows time on the horizontal axis and speed on the vertical axis a straight horizontal line across the graph would indicate
Definition1/7

constant speed

Term1/7
You set up a pulley to help you lift something you anchor the rope at one end and arrange a moveable pulley to achieve a mechanical advantage of 2 by the time you have lifted the object 5m off the gro
Definition1/7

you set up a pulley to help you lift something you anchor the rope at one end and arrange a moveable pulley to achieve a mechanical advantage of 2 by the time you have lifted the object 5m off the ground how much rope have you pulled through the pulley

answer is (10m)

Term1/7
Rate of deceleration are always expressed as
Definition1/7

Rates of deceleration are always expressed as negative numbers.

Term1/7
With regard to the object-lifting examples traced in lesson3 the ima is equal to the distance divided by the distance
Definition1/7

it effort,resistance

Term1/7
Near the end of page 124 of your reading material you are shown a calculation to determine a car's final speed after accelerating for four seconds
Definition1/7

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.
