Question

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.

Answer 1

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 .
