Question

A cheetah can accelerate from rest at the rate of 4m/s2. i) what will be the velocity attained by it in 10s?

Answer 1

Hey friend
here is your
initial velocity = 0 m/sec
final velocity = ? (to find)
acceleration = 4m/sec^2
time = 10 sec
as,
$v = u + at \\ v = 0 + 4 \times 10 \\ v = 40m {sec}^{ - 2}$
so, final velocity after 10 second will be 40 m/sec


glad to help you
hope it helps
thank you.

Answer 2

Answer:

40mper sec.

Explanation:

v (final)=to find.

u (initial)=0m/sec.

time=10 sec

acceleration=4m/sec.

As,. equ. 1.

V=U+at

Now.. putting the values....

V=0+4*10

V=0+40

V=40 m/sec

Hope it's help u....
