Question

A car move 10 m is every one second so its motion is _________________. *

Answer 1

Answer:

uniform motion

Explanation:

pls mark me as brainliest

Answer 2

Answer:

For constant velocity :

Constant velocity u=10 m/s

Time t=10 s

So, displacement in 10 seconds S

1

=ut=10×10=100 m

For accelerated journey :

Initial speed u=10 m/s

Acceleration a=2 m/s

2

Time t=5 s

Displacement in 5 seconds, S

2

=ut+

at

2

⟹ S

2

=10×5+

1

×2×5

2

=75 m

Total displacement in 15 seconds S

total

=100+75=175 m
