Question

a body travels 100m in the first two seconds and 104m in the next 4 seconds. How far it will move in the next 4 seconds if the acceleration is uniform. ​

Answer 1

Answer:

100=2u+2a

u+a=50.......(1)

6u+18a=204...from the first second......(2)

solve (1) &(2):

u=53

a=-3

In total 10 sec distance travelled:

10u+1/2 x a x 10x10=380m , putting all the values:

so distance covered in next four second=380-204=176m
