What represents a case in which you are not accelerating?
KIM [24]

Answer: dv/dt = 0

Explanation: Acceleration has to do with when you are changing velocity. since velocity is a speed and a direction you only accelerate when you change speed or change direction or change both in other words you are not accelerating when you are moving in a constant speed and at a specified direction. E.g driving Eastward at a constant speed of 24m/s, such scenario is a case of not accelerating that is acceleration is zero.

What will happen and give a reason
djyliett [7]

Answer:

1 or 2 or 3

Explanation:

it depends whether the coat is a light or dark colour. if it is lighly coloured it will not absorb heat from the sun and wont melt the snowman. if it is darkly coloured it will be number 1

the coat wont make a difference if the temperature of the snowman is the same and the temperature outside the snoman and the sun isnt shining. the coat would just make him look smart - so number 2

it coul keep in the cold and block out the warmth so number 3

A 10N falling encounters 10N of air resistance (upward force). The net force on the object is:
NemiM [27]

0 N. It's being pushed up the same amount it's being pushed down, so it cancels out.

A baseball approaches home plate at a speed of 44.0 m/s, moving horizontally just before being hit by a bat. The batter hits a p
Luda [366]

Explanation:

It is given that,

Speed of the baseball, u = 44 m/s

Speed of the baseball, v = 53 m/s

Mass of the ball, m = 145 g = 0.145 kg

Time of contact between the ball and the bat, t = 2.2 ms = 0.0022 s

F=ma

F=\dfrac{mv}{t}

F_1=\dfrac{0.145\ kg\times 44\ m/s}{0.0022\ s}

F₁ = 2900 N...........(1)

F=ma

F=\dfrac{mv}{t}

F_2=\dfrac{0.145\ kg\times 53\ m/s}{0.0022\ s}

F₂ = 3493.18 N.........(2)

In average vector form force is given by :

F=F_1+F_2

F=(2900i+(-3493.18)\ N

F=(2900i-3493.18j)\ N

Hence, this is the required solution.
