Can Anyone Answer this Plzz   The answer should be 0.7s

experimentx · Answer

find the distance travelled by the car in 2 s

anonymous · Answer

Is D=2.4m

experimentx · Answer

add 2.7 to it,
and find the final velocity of car

anonymous · Answer

V=2.4m/s

experimentx · Answer

okay ... imagine bolt falling
it will have initial velocity of 2.4 m/s up
acceleration would be 9.8 down
distance = 2.7+2.4 m ... calculate time
if you have done your calculation correctly ... then you must get answer!!
