can someone please help me understand how you do the following problem Theory suggests that T and d are related by the equation T^2 = kd^3+((4pi^2l)/(g)) where g is acceleration due to free fall and k is constant. Use your answers from ... (from that i found that gradient = 20.5, and y-intercept = 0.0670) and the value of l to find values for k and g. Please help I am totally lost.

thank you so much.

yea 7708.8

whoops mean weight

yea got the mass of the lift 4708.8N

are the forces gravity (downwards) and suppourt (upwards)

Hi, can someone please explain to me how you work out tension. Here is an example of the problems I have. A lift of mass 480kg is designed to carry a maximum load of 3000N. Calculate the tension in the lift cable at maximum load when: a)The lift moves down at a steady speed. b)The lift moves downward, accelerating at 1.5ms-2 c)The lift moves upward, accelerating at 1.5ms-2 Thank you so much!

cn sum1 plez explain to me how u work out tension.. thnx soo much:eek:

cn sum1 plez explain 2 me how u cn work out tension??? and how u work out this a car with a mass of 1200 kg accelerates from rest to 8.0m/s, it is towing a tralier with a mass of 200kg. wat is the tension between the car and the trailer when acceleratin? plez explain it 2 me lol i am so confused thnx
