Question

Calculate the distance travelled by the body in 4 second. Velocity is in metre/
ok ​

Answer 1

Explanation:

• dist travelled = area covered by velocity-time graph
• now dist travelled in 4 sec=
• now dist travelled in 4 sec= {(1/2* 1*20)+ (2*20)+ 1/2 *(10+20) +1*10}
• now dist travelled in 4 sec= {(1/2* 1*20)+ (2*20)+ 1/2 *(10+20) +1*10}= 10+ 40+ 15+ 10

now dist travelled in 4 sec= {(1/2* 1*20)+ (2*20)+ 1/2 *(10+20) +1*10}= 10+ 40+ 15+ 10= 75 m ans

hope it helps
