Answer:

The time interval is  t  =  6.667 \ s

Explanation:

From the question we are told that

    The acceleration of the car is  a =  3 m/s^2

     The velocity of the car is  v= 20.0 \ m/s

The final velocity of the car can be mathematically represented as

       v =u + at

Now since the car start from rest  u = 0 So

      v  =  0 + at

       v  =  at

substituting values

       20 =  3 t

       t  =  \frac{20}{3}

        t  =  6.667 \ s

What two factors will make an object stable ​
galben [10]

The position of the centre of gravity of an object affects its stability. The lower the centre of gravity (G) is, the more stable the object. The higher it is the more likely the object is to topple over if it is pushed. Racing cars have really low centres of gravity so that they can corner rapidly without turning over.

Increasing the area of the base will also increase the stability of an object, the bigger the area the more stable the object. Rugby players will stand with their feet well apart if they are standing and expect to be tackled.

A force of 500 N is used to slide a box across a smooth surface; the box moved 5 m in 1.2 seconds. What power is used?
Katen [24]
F = 500N
S = 5m
T = 1.2s
----------------------------------
P = ?

We can use formula P = F * V, just because it was a smooth slide we can assume that average speed was V = S/T = 5 / 1.2 = 50/12

So the final answer would be:

P = F * V = 500 * 50/12

Are you sure those are correct numbers? The answer don't look nice :D
