First law: a body travelling at constant velocity is equivalent to one that is at rest, requiring no resultant force to act on it. y is not accelerating and so F = 0, i.e. there is no resultant force. The maximum force that can be applied to the body is achi.
Newton’s laws of motion Answers © Nick England, Jeremy Pollard, Nicky Thomas & Carol Davenport 2019 9.19 Newton’s Third Law a) The forces on the water and beaker are: their weight 6.8 N; a push down from the suspended weight of 0.6 N; a normal force of 7.4 N from the beaker.
Apr 2, 2019 · 1. mw = 75 kg The normal force exerted by the platform on the weight lifter’s feet is equal to and opposite of the combined weight of the weightlifter and the pumpkin. mp = 275 kg. 9.81 m/s2 = g Fnet = − Fn mwg − = 0 mpg Fn = (mw + mp)g = (75 kg + 275 kg) (9.81 m/s2) Fn = (3.50 × 102 kg)(9.81 m/s2) = 3.43 × 103 N. Fn =.
Newton's Laws Practice Quiz Multiple Choice Identify the choice that best completes the statement or answers the question. 1. After a cannonball is fired into frictionless space, the amount of force needed to keep it going equals a. zero, since no force is necessary to keep it moving. b. twice the force with which it was fired.
Isaac Newton devised the three laws of motion in the 1660s. They describe how an object moves as a result of a force (i.e stationary, at a constant speed or accelerating).
