A physics student on Planet Exidor throws a ball, and itfollows the parabolic trajectory shown in the figure. The ball'sposition is shown at 1.0 s intervals until t = 3.0 s. At t= 1.0 sthe ball's velocity has components v (subscript x) = 3.0 , v(subscript y) = 3.0. Determine the x and y components of the ball'svelocity at t=0, t=2, t=3. What is the value of g on planetexidor?
I know that the x component will be 3 m/s at all times butcan't figure out how to solve for the y component without theacceleration.
A small dense ball with mass 1.5 kg is thrown withinitialvelocity <5,8,0>m/s at time t = 0 at a location wechoose tocall the origin <0,0,0>m. Air resistance isnegligible
(a) When the ball reaches its maximum height, what itsitsvelocit(a vector). It may help to mae a simple diagram
(b) When the ball reaches its maximum height, what is t?Youknow Vy depends on t and you know the initial andfinalvelocities.
(c) Between the launch at t = 0 and the time when theballreaches the maximum height, what is the average velocity? Youknowhow to determine average velocity when velocity changes ataconstant rate.
(d) When the ball reaches its maximum height, what isitslocation(a vector)? You know how average velocity anddisplacementare related.
(e) At a later time the ball's height y has returned toxerowhich means that the average value of Vy from t = 0 to thistime iszero. At this instant, what is the time t.
(f) At the time calculated in part (e),when the ball's heightyreturns to zero, what is x?
