Find the net force exerted on a
0.15-kg ball that has an acceleration of 20 m/s2.

1point) a skydiver weighing 130 lb (including equipment) falls vertically downward from an altitude of 14,000 ft and opens the parachute after 20 s of free fall. assume that the force of air resistance, which is directed opposite to the velocity, is of magnitude 0.85|v|0.85|v| when the parachute is closed and is of magnitude 17|v|17|v| when the parachute is open, where the velocity vv is measured in ft/s. assume that acceleration due to gravity has magnitude 32 ft/s/s; remember that weight is the product of mass and gravitational acceleration. find the speed of the skydiver when the parachute opens. speed is 150.6121788 ft/s find the skydiver's height when the parachute opens. height is 2338.98591 ft find the limiting velocity vlvl after the parachute opens. (think about whether this should be positive or negative.) vl=vl= 7.647 ft/s

If anyonee has done the momentum lab practical in physics can you give me the answers i am s lostt rnn : (

Urgent i will give brainliest farmer dantzler brings her prize pig, penny, to the annual country fair. if the mass of the pig is 140 kg, what is the weight? (what are you solving for? what is your formula? what unit do you use to represent weight? you can do it! ) your a.14 g b.140 n c. 1400 kg d. 1372 n show me how to work it too
