Derive equations of motion?
State and prove triangle law of vector addition.
What is galileo law of odd numbers????
the position of a body moving along x-axis at time t is given by x = (t2-4t+6) m . The distance travelled by body in time interval t = 0 to t = 3 s is -(1) 5 m(2) 7m(3) 4 m(4) 3 m
A ball is thrown vertically upwards with a velocity of 20m/s from the top of a multistorey building. The height of the point from where the ball is thrown is 25m from the ground.
(1) How high the ball will rise?
(2) How long it will be before the ball hits the ground? (Take g=10m/s2
a block of mass of 2 kg is placed on the floor. the coefficient of static friction is 0.4 . a force F of 2.5 N is applied on the block. calculate the force of friction between the block and the floor.
means & full form of w.r.t.
a ball is thrown vertically upward with a speed of 19.6 m/s from the top of a tower and returns to earth in 6 sec find the height of the tower
A particle is moving east-wards with a velocity of 5m/s. in 10 seconds the velocity changes to 5 m/s northwards.What is the average acceleration in this time ?
find unit vector perpendicular to A =2 i +j + k and B = i-j+2k.
if a particle starts moving with acceleration 2m/s2 . what is th distance travelled by it in 5th half second ?
A stone falls freely from rest & the total distance covered by it in last second of its motion equals the distance covered by it in the first 3second of its motion.How long the stone will remain in the air?please show me easy processes.
a train starts from a station with acceleration 0.2 m/s2 on a straight track and then comes to rest after attaining maximum speed on another station due to retardation 0.4m/s2. if total time spent is half an hour, then distance between two stations is {neglect length of train}

A balloon starts rising from the ground with acceleration of 1.25m/s sq . After 8s a stone is released from the balloon . How much time will it take to reach the ground ?(g = 10 m/s sq. )
the resultant of 2 vectors u and v is perpendicular to u and its magnitude is equal to half of v find the angle between u and v?
