Question

2. How long will it take for a ball thrown vertically upward with an initial velocity of

480 km/h to reach its maximum height?

Answer 1

13.33 seconds

Step-by-step 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.
