Question and Answer - Impulse

? A hammer of mass of 1kg moving with a spaced of 6mls stripes a wall and comes to rest in 0.1 S. 1) calculate impulse ii) calculate the average resorcing force that stops the hammer. iii) calculate the average retandation of the hammer? ans: i) my - mu = 1x0-1x6 = 0-6 =-6NS ii) Average retarding force F=FXAL F AP at

F= I -6 Fx0.1 F = 0.1 = -60N 5-01/006 E Fr = -60 a= m F = 60 N = -60/1 - a==60m's r=-a = 60 = com/s2
