Answer 1

Explanation:

v=36 km/hr

v=36×

18

5

=10 m/s

u=0

t=10 sec

v=u+at

10=0+a(10)

10=10a

a=1 m/s

Answer 2

✯G I V E N :-

• Initial velocity(u) is 3m/s
• Final velocity (v)is 37 m/s
• Time taken (t)7s
• Force acting (F)17N

✯To find :-

• Mass of the body

✯ S O L U T I O N :-

In order to find the mass of the body . Firstly we find acceleration of the body then We have the formula of Force from that we can find the mass of the body

Acceleration = Change in velocity/Time

Acceleration = Final velocity - Initial velocity/ Time

a = v - u /t

a =( 37-3)/7

a = 34/7 m/s²

So, acceleration of the body is 34/7 m/s²

Now, In order to find mass of the body We know that,

Force = mass × acceleration

F = m × a

Substituting the values,

17 = m × 34/7

17 × 7 = 34 m

7 = 2m

m = 7/2 kg

m = 3.5 kg

So, mass of the body is 3.5 kg

✯Required Answer :-

3.5 kg
