Question

A motorcycle starts at a speed of 20 m/s and attains 50 m/s in 10 seconds. Calculate acceleration of motorcycle.​

Answer 1

Answer:

70/1 is your right answer

Answer 2

Answer :-

• Acceleration of motorcycle is 3m/s².

⠀⠀⠀━━━━━━━━━━━━━━━━━━━━━━━━━━━

Given :-

Initial velocity of motorcycle is 20m/s

Final velocity of motorcycle is 50 m/s

Time taken by motorcycle is 10 seconds

To Find :-

Acceleration of motorcycle

Solution :-

❍ We can find the acceleration by putting the values in the first equation of motion ::

v = u + at

Where,

• v denotes final velocity
• u denotes initial velocity
• a denotes acceleration
• t denotes time taken

Finding Acceleration :-

=> 50 = 20 + ( a × 10 )

=>  50 = 20 + 10a

 

=> 10a  = 50 - 20  

=> 10a = 30  

=> a = 30/10

=> a = 3m/s²

⠀⠀⠀━━━━━━━━━━━━━━━━━━━━━━━━━━━

• Henceforth, acceleration of motorcycle is 3m/s²
