Question

A body moves with a unifrom acceleration and its velocity is 5m/ s after 10 second its velocity becomes 25 m/s find the acceleration of the body​

Answer 1

Answer:

The total distance travelled is  

=

625

m

Explanation:

The initial velocity is  

u

=

0

m

s

−

1

The acceleration is  

a

=

10

m

s

−

2

The time is  

t

=

5

s

Apply the equation of motion

v

=

u

+

a

t

The velocity is

v

=

0

+

10

⋅

5

=

50

m

s

−

1

The distance travelled in the first  

5

s

is

s

=

u

t

+

1

a

t

2

=

0

⋅

5

+

1

2

⋅

10

⋅

5

2

=

125

m

The distance travelled in the following  

10

s

is

s

1

=

v

t

1

=

50

⋅

10

=

500

m

The total distance travelled is

d

=

s

+

s

1

=

125

+

500

=

625

m

Answer 2

Explanation:

a=v-u/t

a= 25-5/10

a=20/10=2m/s^2
