Final answer:
The speed of the ball after 1 second when thrown upward with a speed of 60 m/s is 50 m/s.
Step-by-step explanation:
To find the speed of the ball after 1 second when thrown upward with a speed of 60 m/s, we need to consider the effects of gravity. The velocity of the ball at any given time can be found using the equation:
final velocity = initial velocity + (acceleration * time)
Since the ball is thrown upward, the acceleration due to gravity will have a negative value (-9.8 m/s^2). Plugging in the values, we have:
final velocity = 60 m/s + (-9.8 m/s^2 * 1 s)
Calculating this, we find that the final velocity of the ball after 1 second is 50.2 m/s. Therefore, the correct answer is 50 m/s (Option B).
