Question

A Ship is moving at a speed of 56 km per hour 1 second laterr it is moving at 58 km per hour what is the acceleration

Answer 1

Given:
Method I:
Initial speed=u=56km/h=56 x 5/18=15.55m/s
Final speed=v=58km/h=58x5/18=16.11m/s
Time=t=1sec
acceleration=a=?
as we know that acceleration is rate of change of velocity.
a=(v-u)/t
=(16.11-15.55)/1
=0.56 m/s²

Method 2:
Initial speed=u=56km/h
Final speed=v=58km/h
Time=t=1/60x60 h
acceleration=a=?
as we know that acceleration is rate of change of velocity.
a=(v-u)/t
=(58-56)/1/60*60
=2x3600
=7200 Km/h²
∴ Acceleration is 0.56 m/s² or 7200 Km/h²
