A softball is thrown from the origin of an X-Y coordinate system with an initial speed of 18 m/s at an angle of 35 degrees above the horizontal. Part A) Find the X positions of the softball at the times t=.50s, 1.0s, 1.5s, and 2.0s. Part B) Find the Y positions of the softball at the times t=.50s, 1.0s, 1.5s, and 2.0s.

myininaya · Answer

thinking 
i haven't taken any physics but this seems kinda calculus like

myininaya · Answer

so at time t_0 we have s speed of 18 m/s and at angle of 35 deg

myininaya · Answer

If the speed is initial then that could mean the speed is changing at other t_i 's

myininaya · Answer

the speed isn't constantly 18 m/s right? that seems what the question is claiming

nincompoop · Answer

or there's something missing 
we can take the derivative of the velocity to obtain the acceleration then apply at the t's required
