Question

Starting from a stationary position Rahul paddling his bicycle to as attain velocity of the 6m/s into30s.the he applies brakes such a velocity of the bycyle comes down to4m/s the next 5s both the case

Answer 1

Answer:

For first case:

Initial velocity =0

Final velocity =60m/s

Time =30sec

v=u+at

6=0+a×30

6=30a

a=306=0.2

a=0.2m/s2

For second case:

Initial velocity =6m/s

Final velocity =4m/s

Time taken =5sec

v=u+at

4=6+a×5

4−6=5a

−2=5a

a=−52

a=−0.4m/s2
