In 1935, a French destroyer, La Terrible, attained one of the fastest speeds for any standard warship. Suppose it took 3.0 min at a constant acceleration of 0.50 m/s2 for the ship to reach its top speed after starting from rest. Calculate the ship’s final speed.
Question
Answer:
Explanation:
From newton’s equation of motion of uniform acceleration
v = u + at
where v is final velocity , u is initial velocity , a is acceleration and time is t .
putting the values
v = 0 + .5 x 3 x 60 ( time in second = 3 x 60 s )
= 90 m /s
So , final velocity is 90 m /s .
