Question

Aakar accelerated from rest at constant rate for first 10 seconds and cover a distance x it covers a distance Y in next 10 seconds at the same acceleration what which of the following is true Asphalt 3 Y equal to 3 X X equal to y y equal to 2x​

Answer 1

Answer:

Y=3X

Explanation:

here u=0 m/s

a=constant

T1=10 sec

therefore by 2nd equation of motion

s=ut+1/2at square

therefore S1 = 1/2a100

=50a=X

in total 20 seconds

S2=1/2a200

=200a

there distance covered from 10th to 20th second is S2-S1=200a-50a=150a=Y

here 3x=Y
