The dumping mechanism used to stop continuous vibration of a vehicle suspension consists of a piston attached to an axle and moving in the cylinder filled with oil.As the axle moves with an initial velocity V, the piston moves and oil is forced through oil surfaces in the piston causing the piston and axle to decelerate at the rate proportional to their velocity
a)Express v in terms of time
b)Express the pistons displacement x in terms of time t
c)Express the velocity in terms of x
A falling body has an initial velocity of 200 cm/seconds. How far will it drop before its velocity becomes 10000 cm/seconds.
A 515kg roller coaster is at the bottom of a loop with a radius of 10m. If the speed at the bottom of the loop is 20m/s, what is the force of the track pushing up on the vehicle at this point?
Is interference a property of some types of waves only or is it a property of all types of waves?
In watching a transverse wave go by, an observer notes that 13 crests go by in a time of 3.0 s. If the distance between two successive crest is measured to be 0.75 m, (a) what is the speed of the wave? (b) What is its period?
If a car,with an initial velocity of 20m/s, accelerates at a rate of 5m/s2 for 3 seconds, what will its final velocity be?
A velocity of magnitude 40m per sec is directed at an angle of 40degree east of north.draw a vector to represent this velocity
