Question

From the v – t graph find.

Velocity at point c

a) Acceleration of the body between A and B

b) Acceleration of the body between B and C

c) Acceleration of the body between C and D
​

Answer 1

Answer:

your answer is here buddy!!

Explanation:

Condition a =

acceleration= DB-OA /OD

= 40-20/3

20÷3

= 6.66 m/s²

condition B=

Here , BC is parallel to time axis therefore there is no acceleration , there is constant velocity.

Condition C.=

in this condition there is no any acceleration is take placing , there is uniform retardation or negative acceleration.

Retardation = CF/ FD

= 40/8

= 5 m/s²
