A is a non-contact breaking of the basketball rules

1 answer:

7 0

A foul occurs when a player or coach breaks a rule covering either contact with an opposing player of unsportsmanlike action. Basketball is a so-called non-contact sport but basketball rules recognize that is not really possible to have 10 players running around a small area without making some contact.

The final velocity of the ice is 82.0 m/s

Explanation:

The chuck of ice in this problem is in free fall, so we can use the following suvat equation for uniformly accelerated motion:

$v^2-u^2=2as$

where

v is the final velocity

u is the initial velocity

a is the acceleration

s is the displacement

In this problem, we have:

u = 0 is the initial velocity of the chuck of ice

$a=g=9.8 m/s^2$ is the acceleration of gravity (we choose downward as positive direction)

s = 343 m is the vertical displacement (the height of the tower)

Solving for v, we find the final velocity of the object:

$v=\sqrt{u^2+2as}=\sqrt{0+2(9.8)(343)}=82.0 m/s$

A swimmer swims 3/5 the width of a river at one velocity, then swims the remainder of the river at half her initial velocity. Wh

SashulF [63]

Let her initial velocity be U.

Let the width of the river be W.

She swims 3/5 the width of the river at U.

Remainder width = (1 - 3/5) = 2/5.

She then swims 2/5 the width with velocity U/2.

Average Speed = (Total Distance Traveled) / ( Total Time Taken).

Distance = Speed * time

time = Distance / Speed.

Time in first trip: = (3/5)W / U =   0.6W/U.

Time in second trip = (2/5)W / (U/2) = 0.4W / 0.5 U = 0.8W/U

Total Distance Traveled = W, width of the river.

Average Speed = W / (0.6W/U + 0.8W/U) = W / (1.4W/U)

   = W * U / 1.4W
      = U/1.4
      = U * 10 / 14
      = (5/7) U.

Therefore Average speed is (5/7) of the initial speed.

A lemming running 3.22 m/s runs off a horizontal cliff. It lands in the water 7.54 m from the base of the cliff. How much time w

LekaFEV [45]

Answer: 2.34s

Explanation:

Given the following :

Horizontal Velocity(V) = 3.22m/s

Horizontal Distance = 7.54m

Therefore, the time spent in the air can be calculated thus:

Using the relation:

Speed = distance / time

3.22m/s = 7.54m / time

Time = 7.54m / 3.22m/s

Time = 2.34s
