MOTION IN A STRIGHT LINE

269813 The variation of velocity of particle moving along a straight lineis shown in the figure. The distance travelled by the particlein $4 s$ is

1

55 m

2

30 m

3

25 m

4

60 m

Explanation:

area of under $v - t$ graph

MOTION IN A STRIGHT LINE

269812 The velocity-time graph of a stone thrown vertically upward with an initial velocity of $30 {ms}^{- 1}$ isshown in the figure. Thevelocity in the upward direction is taken as positive and that in thedownward direction as negative. What is the maximum height to which the stone rises?

1

30 m

2

45 m

3

60 m

4

90 m

Explanation:

$h = \frac{u^{2}}{2 a};$ From graph $u = 30 m / s; a = \frac{30}{3} = 10 m / s^{2}$
