The position of a particle along the x-axis is given in centimeters by x=9.75+1.50t3, where t is
in seconds. Consider the time interval t = 2s to t = 3s and calculate
(a) the average velocity
(b) instantaneous velocity at t = 2s;
(c) the instantaneous velocity when t = 2.5s;
(d) the instantaneous velocity when the particle is mid way between its position at t = 2s and
t = 3s.
Q 2. What will be the distance and displacement while moving in a circle from A to B (along
circular path) and then B to A (along circular path) as shown in adjoining figure?
Q 3. A particles starts from point A with constant speed v on a circle of radius R. Find magnitude
of average velocity during its journey from :-
(a) A to B (anticlockwise)
(b) A to C (anticlockwise)
(c) A to D (anticlockwise)
Q 4. A ball is thrown vertically up with a certain velocity from the top of a tower of height
40 m. At 4.5 m above the top of the tower its speed is exactly half of that it will have at 4.5
m below the top of the tower. Find the maximum height reached by the ball above the
ground?
Q 5. A car accelerates with uniform rate from rest on a straight road. The distance travelled in the
last second of a three second interval from the start is 15 m then find the distance travelled
in first second in m.
Q 6. A body travelling in straight line a travels 2 m in the first two seconds and 2.2m in the next
four seconds with constant retardation. What will be its velocity at the end of the seventh
second from the start?
Q 7. A particle moving in one-dimension with constant acceleration of 10 m/s2 is observed to
cover a distance of 100 m during a 4s interval. How far will the particle move in the next 4s?
