The equation v = a*del_t is sometimes used
to find velocity when acceleration and
time are known. Another form of this
equation is v = v_0 + a*del_t. In this second
form of the equation, the function of the
term v_0 is to:
A. indicate that the equation is valid
only for an object that starts at rest.
B. determine the time at which
velocity is equal to zero.
1. A ball is thrown with an initial velocity of 20 m/s at an angle of 30°
above the horizontal. What is the instantaneous vertical velocity of
the ball when it is 5.1 m above the release point? (g = 9.8 m/s^2)
A text book, world famous and in the most lucid language of Physics. I have studied a few chapters intensively although I own this book [I have purchased this book multiple times due to relocation] You can guess its importance
