Um móvel realiza movimento retilíneo uniformemente
acelerado. Sabe-se que no instante t = 0 seu espaço é 50
m. O módulo da velocidade do móvel tem valor 2 m/s.
Qual a função horária do espaço desse móvel?
A= S=5+10t
B=S = 50 + 2t
C=S = –50 – 2t
D=S = –10 + 5t
E=S = 20 – 2t

The desk has a weight of 75 lb and a center of gravity at g. determine the initial acceleration of a desk when the man applies enough force f to overcome the static friction at a and b. also, find the vertical reactions on each of the two legs at a and at b. the coefficients of static and kinetic friction at a and b are ms = 0.5 and mk = 0.2, respectively

Which of the following best describes the shape of earth's orbit? a.ellipticalb.circularc.spirald.figure eight

Gravity is pulling an object into the sun. the closer the object gets to the sun, the greater the gravitational force that acts on the object, increasing its acceleration. a line graph plotting the speed of the object against time would have which shape? a: straight line of positive slope b: curved line that slopes upward c: curved line that slopes downward d: straight line of negative slope
