Question

A boat initially moving at 10 m/s accelerates at 2 m/s for 10 s. What is the velocity of the boat after 10 seconds?

Answer 1

Answer:

30 m/s

Explanation:

v = u + at

given that,

• u = 10 m/s (initial speed)
• a = 2 m/s^2
• t = 10s
• v =?(final speed)

v = 10 + ( 2 × 10)

v = 10 + 20

v = 30 m/s
