x=at

which of the follwing is true

a. Intial acceleration depends on b only

b Intial velocity depends on c only

c. Intial displacement is d

d. Ratio of intial velocity /intial acceleration depends on a and c

. The displacement of a particle moving in straight line depends on time t as

x=at

Velocity (dx/dt)=3at

Acceleration (d

So Intial displacement(t=0) =d

Intial velolcity(t=0) =c

Intial acceleration (t=0) =2b

v=√x

The displacement of the particles varies with time as

which of the follwing is true

a. t

b t

c. t

d. t

. Given v=√x

or

dx/dt=√x

dx/√x=dt

Integrating both sides between the limit (0,x) and (0,t)

x=t

Hence (a) is correct

At what distance from a train station should the train driver aply the brake so that train stops at the station

a. 800m

b 625m

c. 700m

d. none of these

. we are given

v

a=-2m/s

Now v

0=(50)

a. 25s

b 20s

c. 15s

d. none of these

. Now v=v

0=50-2t

or t=25 sec

Hence (a) is correct

v

a=-2.5 m/s

Both the balls are falling freely under gravity .Therefore no acceleration of one with respect to other .So relative speed of the balls remains constant equal to 40m/s

The Relation between t and distance x is given by

t=ax

Expreess instaneous acceleration in terms of instaneous velocity

acceleration =-2av

a) What is the Car's average speed for the whole journey?

b) What is the Car's average velocity for the whole journey?

50km/h,50km/h

Two balls of different masses (one lighter and other heavier) are thrown vertically upwards; with the same speed. Which one will pass through the point of projection in their downward direction with the greater speed?

In case of motion under gravity, the speed with which a body returns back is always equal to the speed with which it is thrown up. Since expression for final speed does not involve mass, both the balls will acquire the same speed.
