Um balão tem sua trajetória representada pela equação S = 4 x t²-24 x T + 36 A)em que instante o balão passa pela origem(S=0)da trajetoria

B)determine a velocidade no instante T=3s

me ajudem pls

Ameter stick is pivoted at the 0.50-m line. a 3.0-kg object is hung from the 0.15-m line. where should a 5.0-kg object be hung to achieve equilibrium (the meter stick oriented horizontal and motionless)?

In the circuit shown below, with each bulb holding a resistance of 60 ohms, how many amps of current are flowing? express your number as a decimal.

Apulley with mass mp and a radius rp is attached to the ceiling, in a gravity field of 9.81 m/s2 and rotates with no friction about its pivot.
