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

Picture a all traveling at a constant speed around the inside of a circular structure. is the ball accelerating? explain your answer

What is the average speed of a car that travels 40 mph for 1 hour and 60 mph in another hour?

A3030 cmcm wrench is used to loosen a bolt with a force applied 0.30.3 mm from the bolt. it takes 6060 nn to loosen the bolt when the force is applied perpendicular to the wrench. how much force would it take if the force was applied at a 3030 degree angle from perpendicular? a 3030 cmcm wrench is used to loosen a bolt with a force applied 0.30.3 mm from the bolt. it takes 6060 nn to loosen the bolt when the force is applied perpendicular to the wrench. how much force would it take if the force was applied at a 3030 degree angle from perpendicular?
