Aball is rolling down a hill at +1.0m/s the ball is uniformly accelerating at +4.9m/s^2 what will the balls velocity be 4.0 later

we are given

initial velocity is +1.0 m/s

so,

Let's assume final velocity as v

uniformly accelerating at +4.9m/s^2

so,

time is 4 sec

so, t=4 s

now, we can use formula

we can plug values

...............Answer

So velocity of ball after 4 sec will be 20.6 m/sec

Step-by-step explanation:

We have given initial velocity of the ball u = 1 m/sec

Acceleration of the ball

We have to find velocity after 4 sec

So ti,e t = 4 sec

According to first equation of motion we know that v = u+at

So

So velocity of ball after 4 sec will be 20.6 m/sec

answer is:

1.75 pounds

ok
