Answer:
13.33 seconds
Explanation:
At maximum height, the equation of motion becomes:
v = u + at
Since the object was thrown vertically, the initial velocity (u) is zero and the acceleration (a) becomes the acceleration due to gravity (10 m/s2). The equation becomes:
v = at
v = 480 km/hr = 133.333 m/s
10t = 133.333
t = 133.333/10
t = 13.33 seconds.
The time for the ball thrown vertically with a velocity of 480 km/hr to reach the maximum height is 13.33 seconds.
