1) a 0.86kg cart is connected to a 50 gram mass via string over a pulley. calculate the tension of the string when the cart is held in place2) calculate tension once the cart has been released 1) a 0.86kg cart is connected to a 50 gram mass via string over a pulley. calculate the tension of the string when the cart is held in place
2) calculate tension once the cart has been released 1) a 0.86kg cart is connected to a 50 gram mass via string over a pulley. calculate the tension of the string when the cart is held in place
2) calculate tension once the cart has been released
Explanation / Answer
Cart and the Mass is attached to the Pulley with the string where Mass must be hanging.
a) As Weight of Mass will balance the Tension of the string when the cart is held in place
T = mg
= 0.05*9.8
= 0.49 N
b) when the cart has been released with acceleration 'a'
mg - T = ma ...............net force downward on mass of 50 g
T = Ma = 0.86a ...............net force on cart
0.49-0.86a = 0.05a
a = 0.49/0.91 =0.538 m/s2
Tension on cart = 0.86*0.538 = 0.46307 N
