Suppose the stone is thrown at an angle of 30.0� degrees below the horizontal. If it strikes the ground 57.0 m away,

Question

find (a) the time of flight, (b) the initial speed, and (c) the speed and the angle of the velocity vector with respect to
the horizontal at impact. (Hint: For part (a), use the equation for the x-displacement to eliminate v0t from the equation
for the y-displacement.)
the height which it thrown from is 45m

Answer 1

show me the answer

Answer 2

1.57 m/s
41.9 m/s
51.3 m/s, 45 degrees
