Question

A body initially at rest, start moving with a constant acceleration 2m/ssquare .Find velocity and distance travelled in 5 sec​

Answer 1

Answer:

initial velocity=0 since body at rest

acceleration=2m/s square

time =5s

by v=u+at

v=0+2*5

v=10m/s

by applying v^2=u^2+2as

10^2=0^2+2*2*s

100=0+4s

100/4=s

25m=s

Answer 2

Answer:

here

u=0

a=2m/s

t=5sec

we know that

v=u+at

v= 0+2×5

v=10m/s

now by applying 3rd equation

of motion

v^+u^=2as

10^+0^=2×2×s

100+0=4×s

s=100/4

s=25m
