CBSE Class 11-science Answered

A balloon is ascending at the rate of 12 m/s. When it is at a height of 65 m from the ground a packet is dropped from it, does the packet reach the ground? Take g= 10 m/s square.
Asked by | 21 Aug, 2012, 12:06: AM
Expert Answer
initial velocity of packet = -12m/s  (taking up direction as negative)
acceleration, a = 10m/ss
height, h = 65m
thus using second equation of motion you can find out the time taken and of course the packet will reach the ground.

A particle travels in a straight line, such that for a short time 2s≤t≤6s, its motion is described by v=(4/a) m/s, where a is in m/s 2 . If v =8m/s when t = 2s, determine the particle's acceleration when t = 4s.
