A basketball is thrown with an initial upward velocity of feet per second from a height of feet above the ground. the equation m

odels the height in feet t seconds after the basketball is thrown. after the ball passes its maximum height, it comes down and then goes into the hoop at a height of feet above the ground. about how long after it was thrown does it go into the hoop?

The answer is t=1.29 seconds.

<h3>What is Velocity?</h3>
  • The rapidity of movement or operation; swiftness; speed: a high wind velocity. Mechanics. the time rate of evolution of position of a body in a specified demand. the rate of speed with which something happens; rapidity of movement or reaction.
  • Velocity is the prime hand of the position as well as the rapidity of the object. It can be characterized as the distance covered by an object in a unit of time. Velocity can be defined as the displacement of an object in a unit of time.
  • Velocity (v) is a vector amount that measures displacement (or change in position, Δs) over the change in time (Δt), described by the equation v = Δs/Δt. Speed (or rate, r) is a scalar amount that measures the distance traveled (d) over the transformation in time (Δt), represented by the equation r = d/Δt.

A rubber-wheeled 50 kg cart rolls down a 35 degree concrete incline. Coefficient of rolling friction between rubber and concrete
lapo4ka [179]

Answer:

(a) 5.62 m/s²

(b) 5.46 m/s²

Explanation:

The given values are:

mass,

m = 50 kg

angle

= 35°

(a)

If friction neglected,

⇒ F_x=mgSin \theta=ma

⇒ a_x=gSin \theta

       =9.8 \ Sin35^{\circ}

       =5.62 \ m/s^2

(b)

If friction present,

⇒ F_x=mgCos \theta

⇒ F_x=mgSin \theta-\mu_r mgCos \theta

⇒ a=gSin \theta-\mu_rgCos \theta

      =9.8 \ Sin35^{\circ}-0.02\times 9.8 \ Cos30^{\circ}

      =5.46 \ m/s^2

Which one of the following indicates a drop in temperature?
Nitella [24]
Answer: <span>D. A bimetallic strip bends so that the steel is on the outside curve
</span>
When something has an increased temperature, its volume will expand. Then, if the temperature drops, its volume should be smaller. From there option A and B are out since the liquid in thermometer is expand or move up.

When you put two kinds of different metal with a different coefficient of thermal expansion, the outer curve metal will be the one with lesser coefficient when temperature drop. Since the question about drop in temperature then the metal should be bend
Brass will expand 1.5 times more than the steel so the outer curve would be the steel.

Numerical Problems:
dangina [55]
  • Displacement=1200m
  • Time=4min=4(60)=240s

\boxed{\sf Velocity=\dfrac{Displacement}{Time}}

\\ \sf\longmapsto Velocity=\dfrac{1200}{240}

\\ \sf\longmapsto Velocity=5m/s
