Question

A particle of mass 1 kg is moving in
straight line
and its acceleration is 5 m/ s Work done by
n=0 to n =10m is​

Answer 1

Answer:

• Work done by particle = 50 Joules

Given:

• Mass of particle, m = 1 kg
• Particle is moving in a straight line
• Acceleration of particle, a = 5 m/s²
• Displacement of particle, s = 10 m  

To find:

• Work done by particle, W =?

Formulae required:

• Formula to calculate force

      F = m a

• Formula to calculate work done

      W = F s

[ Where F is force, m is mass, a is acceleration, W is work done and s is displacement of a body ]

Solution:

• Let, force applied on particle be F

Using formula

→ F = m a

→ F = ( 1 ) × ( 5 )

→ F = 5 N

Now, Using formula

→ W = F s

→ W = ( 5 ) ( 10 )

→ W = 50 J

Therefore,

• Work done by Particle is 50 Joules.
