Question

A ship is moving at a speed of 56 km/h. One minute later, it is moving at 58 km/h. What is its acceleration?

Answer 1

Answer:

0.009259 m/s²

Explanation:

Given :

• Initial velocity = u = 56 km/hr

• Final velocity = v = 58 km/hr

• Time taken = t = 1 minute = 60 seconds

To find :

• Acceleration of the ship with which it is moving

u = 56×5/18 = 140/9

v = 58×5/18 = 145/9

t = 60 seconds

Acceleration = (v-u) / t

Acceleration = (145/9 - 140/9)/60

Acceleration = (5/9)/60

Acceleration = 5/9×1/60

Acceleration = 5/540 m/s²

Acceleration = 0.009259 m/s²

The acceleration of the ship is equal to 0.009259 m/s²

_______________

${ \huge{ \bold{ \underline{ \underline{ \purple{Answer:-}}}}}}$

✒Given : -

• Final Velocity(v) = 58 km/h
• Initial Velocity(u) = 56 km/h
• Time Taken(t) = 1 min. (60 seconds)

✒To Find : -

• Acceleration = ?

✒On Calculating : -

➫u = 56 × 5/18 = 140/9

➫v = 58 × 5/18 = 145/9

➫t = 60 sec.

✒Formula Used : -

$\leadsto\sf{{ \small{ \bold{ \bold{ \bold{ \red{Acceleration=\dfrac{(v-u)}{t}}}}}}}}$

✒Now ,

➫ a = (145/9 - 140/9)/60

➫ a = (5/9)/60

➫ a = 5/9 × 1/60

➫ a = 5/540 m/s²

➫ a = (5/9)/60

➫ a = 5/9 × 1/60

➫ a = 5/540 m/s²

$\leadsto\sf{{ \large{ \boxed{ \bold{ \bold{ \orange{0.009259{m/s}^{2}}}}}}}}$

➴So , the acceleration of the ship is 0.00925 ..
