Newton throws an apple straight up at 10 m/s. What is the ball's velocity
after 1.4 seconds?

23.72m/s

Explanation:

The final velocity can be calculated using the formula:

V = u + at

Where; v = final velocity (m/s)

u = initial velocity (m/s)

a = acceleration due to gravity (m/s²)

t = time (s)

Based on the provided information, u = 10m/s, t = 1.4s, a = 9.8m/s²

V = 10 + (9.8 × 1.4)

V = 10 + 13.72

V = 23.72m/s
