A bomb dropped from a balloon reaches the ground in 30seconds.Determine the height of the balloon if it is ascending with a speed of 100cm^-1 when the bomb is dropped.

800cm3 of gas was collected at temperature of 33 degree and pressure of 500mmHg. Convert the volume of gas at S.T.P

A particle starts from rest and accelerate to velocity of 5m/s in 30s it maintains this velocity for 20s and decelerates to rest in a further 15s I. Draw a velocity time graph of this motion ii. Calculate the initial acceleration of the particle iii. Calc...
