Question

Please help with this quiz problem On earth a ball is thrown with V initial = 5i +19.6j (a) Find Ymax and Tymax, the maximum eigt achieved by the balland the time the ball reaches maximum height, respectively (b) Find the equation of vertical motion Y(t) and theequation of horizantal motion X(t)    Please help with this quiz problem On earth a ball is thrown with V initial = 5i +19.6j (a) Find Ymax and Tymax, the maximum eigt achieved by the balland the time the ball reaches maximum height, respectively (b) Find the equation of vertical motion Y(t) and theequation of horizantal motion X(t)   

Explanation / Answer

At max height velocity is 0 v= vo +at 0= 19.6 -9.8 t t= 2 sec y= vot +1/2 at^2 y= 19.6 (2) -4.9 (2)^2 y= 19.6 m b) same equation as before d= vot +1/2 at^2 Y(t) = 19.6 t -4.9 t^2 X(t)= 5t
