Since, cart is released at its maximum displacement as, x=0.10 m So, oscillation of the block would follow the cosine function like x=Acos(wt) A= amplitude = 0.10 m and angular frequency is defined as, 0=4 here T= time period then, above equation could be written as, x=Acos(274
(a) now, when t= 2.7 s then, x=Acos(244) x=0.1m cos 2017 x=0.1m cos(7.065 rad) x=0.071 m = 7.1 cm Ans. (b) when t=3.0 s then,
x=0.01 m cos 20 3.0 (2.4s) x=0.01 m cos(7.85rad) x = 0 m Ans. (C) when x=-5 cm = -0.05 m then, from the equation, -0.05 m=0.1
2.710 = cos**(-0.5) t=0.8 sec time period of the pendulum is defined as, T=211 1= length of the pendulum
then, let's plug the value we get as, 1_ (2.0 s)?(9.8m/s?) 4(3.14) l=0.994m-1.0m Ans.
