A body leaving a certain point O moves with an acceleration which is constant.. At the end of the fifith second it's velocity is 1.5m/s. At the end of the sixth second the body stops and starts to move backwards. Find the distance traversed by the body before it comes to rest. What is the velocity with which it returns to O?

A beach ball, moving at a speed of 1.27 m/s, rolls off a pier and hits the water 0.75 m away from the end of the pier. How high above the water is the pier?

A bridge is 176.4 m above a river. If a lead-weighted fishing line is thrown from the bridge with a horizontal velocity of 22.0 m/s, how far has it moved horizontally when it hits the water?

Adding vectors Algebraically: Find the vector components along the directions noted in parenthesis.

1. a car displaced 45°north of east by 10.0km (north and east)

A person standing at the edge of a cliff kicks a stone over the edge with a speed of 18m/s . The cliff is 52m above the water. How long does it take for the stone to fall to the water? With what speed does it strike the water?

sir i have to ask that...are we have a complete example of equilibruim?
examples explained by our teachers i not understood plz give me complete example i shall be very thank full to you....thanks

a particle is thrown vertically upwars. its velocity at half of the height is 10m/s.what is the mximum height attained by it ?

A box is given a push so that it slides across the floor. How far will it go, given that the coefficient of kinetic friction is 0.20 and the push imparts an initial speed of 4.0 m/s. I know the answer I just am lost as to how to solve it

how to find final height in a work, kinetic energy problem with only the initial velocity, initial height and an angle? The object goes off a ramp with some projectile motion.

How do you solve a problem for frictional work on an incline with only the mass, angle, beginning and end velocity and height?
