Answer:
30 m/s
Step-by-step explanation:
A boat moves initially at 10 m/s
The boat accelerates at 2 m/s^2 for 10 seconds
We are required to calculate the final velocity (v)
Therefore the velocity of the boat can be calculated as follows
v = u + at
u= 10 m/s
a= 2 m/s^2
t= 10 seconds
v= 10 + 2(10)
v= 10 + 20
= 30 m/s
Hence the velocity of the boat after 10 seconds is 30 m/s
