A tiger leaps horizontally out of a tree that is 6.00 m high. If he lands 2.00 m from the base of the tree, calculate his initia
Musya8 [376]

Answer:

The initial speed of the tiger is 1.80 m/s

Explanation:

Hi there!

The equation of the position vector of the tiger is the following:

r = (x0 + v0 · t, y0 + 1/2 · g · t²)

Where:

r = position vector at a time t.

x0 = initial horizontal position.

v0 = initial horizontal velocity.

t = time.

y0 = initial vertical position,

g = acceleration due to gravity.

Let´s place the origin of the frame of reference on the ground at the point where the tree is located so that the initial position vector will be:

r0 = (0.00, 6.00) m

We can use the equation of the vertical component of the position vector to obtain the time it takes the tiger to reach the ground.

y = y0 + 1/2 · g · t²

When the tiger reaches the ground, y = 0:

0 = 6.00 m - 1/2 · 9.81 m/s² · t²

2 · (-6.00 m) / -9.81 m/s² = t²

t = 1.11 s

We know that in 1.11 s the tiger travels 2.00 m in the horizontal direction. Then, using the equation of the horizontal component of the position vector we can find the initial speed:

x = x0 + v0 · t

At t = 1.11 s, x = 2.00 m

x0 = 0

2.00 m = v0 · 1.11 s

2.00 m / 1.11 s = v0

v0 = 1.80 m/s

The initial speed of the tiger is 1.80 m/s

ICE Princess25 [194]

A particle with charge -40.0nC is on the x axis at the point with coordinate x=0 . A second particle, with charge -20.0 nC, is on the x axis at x=0.500 m.

No, there is no point at a finite distance where the electric potential is zero.

Hence, Option D) is correct.

What is electric potential?

Electric potential is the capacity for doing work. In the electrical case, a charge will exert a force on some other charge and the potential energy arises. For example, if a positive charge Q is fixed at some point in space, any other positive charge when brought close to it will experience a repulsive force and will therefore have potential energy.

It is also defined as the amount of work required to move a unit charge from a reference point to a specific point against an electric field.

If a ball is thrown vertically upward from the roof of 32 foot building with a velocity of 64 ft/sec, its height after t seconds
stepan [7]

Answer:

a) s_{max} = 96\,ft, b) v(4.449\,s) = -78.368\,\frac{ft}{s}

Explanation:

a) The maximum height is obtained with the help of the First and Second Derivative Tests:

First Derivative

v(t) = 64 - 32\cdot t

64 - 32\cdot t = 0

t = 2\,s

Second Derivative

a(t) = -32 (absolute maximum)

The maximum height reached by the ball is:

s (2\,s) = 32 + 64\cdot (2\,s) - 16\cdot (2\,s)^{2}

s_{max} = 96\,ft

b) The time required by the ball to hit the ground is:

32+64\cdot t - 16\cdot t^{2} = 0

-16\cdot (t^{2}-4\cdot t - 2) = 0

t^{2}-4\cdot t - 2 = 0

(t -4.449)\cdot (t+0.449)\approx 0

Just one root offers a solution that is physically reasonable:

t = 4.449\,s

The velocity of the ball when it hits the ground is:

v(4.449\,s) = 64 - 32\cdot (4.449\,s)

v(4.449\,s) = -78.368\,\frac{ft}{s}
