1.) Compute the velocity of an earth satellite whose distance is 4.5x107 m. Ans. 10717.

9 kph
2.) A particle is traversing a curved path of radius of curvature 300 m with a speed of 108
kmph and a tangential acceleration 4 m/s 2. The total acceleration of the particle is
__________. Ans. 5 m/s2
3.) A fighter plane flying in the sky dives with a speed of 120 m/s in a vertical circle of
radius 100 m. Mass of pilot is 80 kg. Force with which the pilot presses the seat at the
highest position is __________. Ans. 10720 N

For free fall,


1.) Two balls are dropped from the same point after an interval of one second. If acceleration
due to gravity is 10 m/s 2, their separation of 3 seconds after the release of first ball would
be _________. Ans. 25 m
2.) A plane dropped a bomb at an elevation 1000 meters from the ground intended to hit a
target which elevation is 200 m from the ground. If the plane was flying at a velocity of
300 kph, at what distance from the target must the bomb be dropped to hit the target?
Wind velocity and atmospheric pressure, to be disregarded. Ans. 1064.2 m
3.) It was discovered that the acceleration due to gravity on the moon is 1.67 m/s 2. John can
throw a stone 12 m straight upward on earth, how high should he able to throw a stone on
the moon? Assume that the throwing speeds are the same in the two cases. Ans. 70 m
