Question

A ship is traveling at 154 m/s and accelerates at a rate of 1.80 m/s^2 for 1 minute. What will its speed be after that minute? Calculate the answer in both meters per second and kilometers per hour.

Answer 1

Given:

u(initial velocity): 154 m/s

accelerates (a): 1.8 m/s^2

t= 1 min=60 secs

Now we know that

s= ut + 1/2(at^2)

s= 154 x 60 + (1.8 × 60 ×60) ÷ 2

s= 12,480 m
