OBLIQUE THROW IN VACUUM

A body is thrown obliquely into the vacuum at an initial velocity of 100 m / s, in a direction that forms with the horizontal an angle x, such that sin (x) = 0.8 and cos (x) = 0.6. Adopting g = 10m / s², determine:

(a) the horizontal and vertical velocity component modules at the moment of launch;

(b) the instant at which the body reaches the highest point of its trajectory;

c) the maximum height reached by the body;

d) The range of the throw.

object is projected with an initial velocity u at an angle to the horizontal direction.

We assume that there is no air resistance .Also since the body first goes up and then comes down after reaching the highest point , we will use the Cartesian convention for signs of different physical quantities. The acceleration due to gravity 'g' will be negative as it acts downwards.

h=v_ox*t-g*t^2/2

l=v_oy*t

Flip Flap Railway (1895): der Schlitten einer Achterbahn fährt zuerst eine schiefe Ebene hinunter, dann in einen kreisförmigen Looping und am Schluss horizontal weg. Die Bewegung ist auf den Schwerpunkt reduziert und vom Impuls wird nur der Betrag betrachtet. Demenstprechend beziehten sich die G-Kräfte gemessen in g auf diesen Punkt.

Uma roda-gigante de raio 14 m gira em torno de um eixo horizontal. Um passageiro sentado em uma cadeira, move-se com velocidade linear v=7 m/s. Determine:

a) a velocidade angular do movimento.

b) gráfico XY do movimento da cadeira.

c) em quanto tempo o passageiro executa uma volta completa.
