1. The problem statement, all variables and given/known data A 900-kg car is pulled by a constant force of 1800N. Assume friction on the road surface is negligible. a) What is the acceleration of the car? b) If the car starts from rest, what is its speed after 10s? c) What is the average velocity of the car during the 10s? d) What is the distance traveled in the 10s? e) What is the work done by the pull force in the 10s? f) What is the kinetic energy of the car at the end of the 10s? g) If the call falls off a cliff of height 200cm at the end of the 10s, what is its kinetic energy right before it lands? 2. Relevant equations vf = vo + at x = vot + 1/2at2 vf2 = vo2 + 2ax F = ma 3. The attempt at a solution a) F=ma 1800N= (900kg)(a) a= 2 m/s2 b) vf = vo + at vf = (2 m/s2)(10 s) vf = 20 m/s c) I am not sure what the differnce is between questions b and c d) x = vot + 1/2at2 x = 0 + 1/2(2 m/s2)(10s)2 x = 100 m e) 1800N times 100m = 18000 J but I am not sure of this one f) I need help with this one g) I need help with this one too =( I truly appreciate any help you can offer!
