An object is pushed from rest across a sheet of ice, accelerating at 8.0 m/s^2 [E] over a displacement of 1.05 m [E]. The object then slides at a constant velocity for 6.0 s until it reaches a rough section that causes the object to stop in 2.5 s.

Explanation:

From the question we are told that:

Acceleration

Displacement

Initial time

Final Time

Generally the equation for Velocity of 1.05 travel is mathematically given by

Using Newton's Law of Motion

Generally the equation for Distance traveled before stop is mathematically given by

Generally the equation for Distance to stop is mathematically given by

Since For this Final section

Final velocity

Initial velocity

Therefore

Using Newton's Law of Motion

Giving

Therefore

Generally the Total Distance Traveled is mathematically given by

he made 11 calls in one day

when jerome paddle in flowing river towards east the net speed of jerome will increase

so the net speed of jerome will be given as

now the speed of paul will be same as it is given as he is running on the ground

so

so here we can say since the speed of jerome is more so he will win the race

now as we know the distance so the time difference is given as

so jerome will reach first and the time difference will be 203.55 s or 3.4 min
