Question

a body starts with an initial velocity of 20ms and acceleration 5m/S2. find the distance covered by it in 5s​

Answer 1

Answer:

175m

Explanation:

u=20m/s

a=5m/s2

t=5s

S=?

as we know,

S=ut+1/2at2

=20×5+1/2(5)25

=100+150/2

=350/2

=175m

Thank you.

Answer 2

Explanation:

u= 20ms , v =? , a= 5 m/s*2 as t= 5s so

a= v-u÷t

5=x-20÷5. let v = x

25+20= x

45 ms = x

45ms = v
