Hunting from a boat is very enjoyable but a sportsman should consider these things when hunting from a boat, to make the hunting successful and safe.
Safety: hunting from the boat can be dangerous, safety is one of the important thing. So, safety measures put in first place.
Communication means: if boat goes to deep water, before getting any problem, one should have many types of means of communication.
Hunting tools: you should keep different types of hunting tools.
One should know the kind of water, keep food with you and should know all the directions about it.

A baseball pitcher makes a big mistake and throws the ball straight up. If it reaches a maximum height of 15 m find the initial
borishaifa [10]

Answer:

17.15 m/s.

Explanation:

The following data were obtained from the question:

Maximum height (h) = 15 m

Final velocity (v) = 0 m/s

Acceleration due to gravity (g) = –9.8 m/s² (since the ball is going again gravity)

Initial velocity (u) =.?

The initial velocity with which the baseball pitcher threw the ball can be obtained as follow:

v² = u² + 2gh

0² = u² + (2 × –9.8 × 15)

0 = u² + (–294)

0 = u² – 294

Collect like terms

0 + 294 = u²

294 = u²

Take the square root of both side

u = √294

u = 17.15 m/s

Therefore, the baseball pitcher threw the ball with an initial velocity of 17.15 m/s

If a system requires 150 j of input work and produces 123 J of output work, whats its effiency
Yuki888 [10]

The effiency of a machine is

                 (output work or energy) / (input work or energy) .

For the system described in the question, that's

                 (123 J) / (150 J) = 0.82  =  82% .

An object is released from rest at time t = 0 and falls through the air, which exerts a resistive force such that the accelerati
lubasha [3.4K]

Answer:

The correct option is

a. v = g (1-e^{-bt})/b

Explanation:

Time at which the object start fall t = 0

The acceleration a is given by a = g - bV

Where V = Speed of the object

Speed V² = u² + 2·a·h

However with the drag force the object will approach terminal velocity as t becomes progressively larger whereby v will stop increasing

Option a. is the only option that has  limiting value of v which is in the range of g as t increases ∴ option a. is the correct option.

v = g (1-e^{-bt})/b  as t increases (1-e^{-bt}) → 1 s and v→ g/b m/s

melamori03 [73]

Answer:

a_r=389\ rev.s^{-2}

n=58350 rev

Explanation:

Given:

time of constant deceleration, t=10\ s

A.

initial angular speed, N_i=3890\ rpm\

<u>Using equation of motion:</u>

N_f=N_i+a_r.t

0=3890+a_r\times 10

a_r=389\ rev.s^{-2}

B.

Using eq. of motion for no. of revolutions, we have:

n=N_i.t+\frac{1}{2} a_r.t^2

n=3890\times 10+0.5\times 389\times 100

n=58350\ rev
