A particle starts with an initial velocity 2 m/s along the positive x direction and it accelerates uniformly at the rate 1m/s2. Find the following:
(a) Distance traveled by it in the first two seconds
(b) How much time it take to reach the velocity of 5 m/s
(c) How much distance will it cover in reaching the velocity 5 m/s

Expert Answer:
we have
(a) S = ut +1/2 a t2
= 2 
2 + ½ 1 (2)2
2 + ½ 1 (2)2 = 4 + 2
= 6m
(b) Time taken to reach the velocity of 5 m/s is:
v = u + at
5 = 2 + 1 t
tt = 3 seconds
(c) Distance covered on reaching the velocity of 5 m/s is:

- Formula to find distance travelled by an uniformly accelerated body is
- The distance x covered by a body moving in a straight line in time t is given by the relation- 2x²+3x=t If v is the velocity of body at a certain instance of time, find it's acceleration.
- eg. v = 2x ; assume t = 0 ; x = 2 m ; find a(t)?
- Define instantaneous acceleration.
- The velocity of the particle is given by v = 4t2 + 7 cm/s. Find the velocity of the particle during the time interval t1 = 2s and t2 = 4s also find the average acceleration during the same interval of time.
- The displacement of a particle along x-axis is given by x = 4 + 6t + 5t2. Obtain its velocity and acceleration at t = 2s.
- What does the slope of a line on velocity-time graph reveals about the acceleration of the object?
- Give any three information about the motion of an object with help of given figure.
- What does this graph indicate about the motion of an object?
