Question

A cyclist was moving at a speed of 5m/sec and picks up a speed of 10m/sec in a distance of 50 m what is its acceleration?

Answer 1

v2-u2=2as
100-25=2*a*50
75=100a
a=3÷4=0.75m per second sq.

Answer 2

U= 5m/s

V=10m/s

S=50m

We know,

2as=v^2-u^2

A=(10×10)-(5×5)/2×50

A=75/100

A=0.75m/s2

We know

A=v-u/t

75/100×t=10-5

T=3.75 seconds
