An object is thrown directly up (positive direction) with a velocity (vo) of 20.0 m/s and do= 0. How high does it rise (v = 0 cm
/s at top of rise). Remember, acceleration is -9.80 m/s2.d = _________ mA. 1.02B. 2.04C. 20.4D. 40.8
1 answer:
The object rises to a height of 20.4 m. So option C is correct.
Explanation:
initial velocity= Vi=20 m/s
final velocity at the top= Vf=0
acceleration= g=-9.8 m/s²
Vf²=Vi²+2gh
0= (20)²+2 (-9.8)h
-200=-9.8h
h=200/9.8
h=20.4 m
Thus the object rises to a height of 20.4 m
