Question

Plot the speed vs time graph on the graph paper using the given data and answer the
questions below the table:

(i) Calculate acceleration for t= 0 s to t = 50s
(ii) Calculate total distance covered by the object.​

Answer 1

Answer:

ANSWER

Distance covered is equal to the area under velocity-time graph.

Distance in last two seconds s

×8×(6+2)=32 m

Fraction of the distance covered by the body in the last two seconds of its motion to total distance traveled by it in all the seven seconds is 8/32=1:4
