Question

good morning friends.....plz solve it...i will give uh 15 thanks...❤​

Answer 1

Answer:

4 ) slope will be straight line ( constant ) .

5) v² = u² + 2as

v² = 25

v = 5 m/s .

therefore ,

v = u + at

t = 10 sec .

Answer 2

4th AnSwer :-

the slope is constant.

Displacement-time graph of a body moving with uniform velocity is always a straight line with slope =0.

5th AnSwer :-

Given :-

⇢Accerlation, a = 0.5m/s²

⇢distance travelled, s = 25m

⇢initial velocity, u = 0m/s

To find :-

a) final velocity, v

b) time taken, t

Solution :-

a) using equation of motion .i.e.,

➠ v² = u² - 2as

➠ v² = 0² - 2(0.5)(25)

➠ v² = 25

➠ v = √25 = 5m/s

Thus, the final velocity of the car is 5m/s.

b) using the equation of motion .i.e.,

➠ v = u + at

➠ 5 = 0 + (0.5)(t)

➠ t = 5/0.5

➠ t = 10sec

Thus, the time taken is 10sec
