You can describe the _______________ of an object by saying it is moving in a straight line or is curved around another object.

velikii [3]

Answer:

You can describe the motion of an object by saying it is moving in a straight line or is curved around another object. You can also describe where an object is by its position in relation to another object. The second object acts as a reference point. When an object changes position, you know it has motion. Motion can also be described by finding an object's speed or how fast or slow it moves in a certain amount of time. In addition, you can describe the object's speed AND direction together. This is called velocity

Explanation:

In the given answer-

Motion is defined as - the change in the movement or position of any object or body.

Position is said to be a place or somewhere or a location where any object or body is particularly placed/located or put on.

Reference point is a fixed point with regards to which any object or body changes its position. It is also called reference origin.

Speed is defined as the rate of any object covering certain distances. It is a scaler quantity (quantity which depends upon only magnitude).

Velocity is defined as the rate of speed per unit time. It is a vector quantity (quantity depending upon both magnitude and direction ).

If a car used 260.000 W of power to complete a race in 15 s. how much work did the car do?

marta [7]

Work done by the car is 3900 J

Explanation:

Power and work are related by the equation, Power = Work Done/Time
Power is the rate at which work is done.
Here, the car uses power of 260 W and time taken is 15 s.

Work Done = Power × Time

= 260 × 15 = 3900 J

A daring 510-N swimmer dives off a cliff with a running horizontal leap. What must her minimum speed be just as she leaves the t

oee [108]

Answer:

$v_x = 1.26 m/s$

Explanation:

given,

weight of swimmer = 510 N

length of ledge, L = 1.75 m

vertical height of the cliff, h = 9 m

speed of the swimmer = ?

horizontal velocity of the swimmer should be that much it can cross the wedge.

distance = speed x time

d = v_x × t

1.75 = v_x × t ........(1)

now,time taken by the swimmer to cover 9 m

initial vertical velocity of the swimmer is zero.

using equation of motion for time calculation

$s = ut +\dfrac{1}{2}gt^2$

$9= 0+\dfrac{1}{2}\times 9.8\times t^2$

t² = 1.938

t = 1.39 s

same time will be taken to cover horizontal distance.

now, from equation 1

1.75 = v_x × 1.39

$v_x = 1.26 m/s$

horizontal speed of the swimmer is equal to 1.26 m/s
