A boat with an initial speed of 5.0 m/s accelerates at a uniform rate of 1.2 m/s2 for 5.0 s. What is the final speed of the boat during this time? (P.4B)
A. 6.0 m
B. 6.2 m
C. 11 m/s
D. 26 m/s

v = 11 m/s

Explanation:

Given tha,

Initial speed, u = 5 m/s

Acceleration, a = 1.2 m/s²

Time, t = 5 s

We need to find the final speed of the boat during this time. Let it is v. Using first equation of motion as follows :

v = u +at

Putting all the values, we get :

v = 5 + 1.2(5)

v = 11 m/s

So, the final speed of the boat is 11 m/s. Hence, the correct option is (c).

the answer is 46 mls because when you add the speed per second it increses the speed

it becomes positively charged by charging it
