A ball is thrown forward at 5 m/s. How would the path of the ball differ on Earth than on the moon? The ball would follow a curv

ed path on Earth but a straight path on the moon. The ball would follow the same curved path on Earth as on the moon. The ball would curve down more sharply on Earth than on the moon. The ball would curve down on Earth but curve up on the moon.

A boat moves through the water with two forces acting on it. One is a 1,800-N forward push by the water on the propeller, and th
baherus [9]

(a)The acceleration of the 1,400-kg boat will be 0.425 m/sec²

(b) If it starts from rest, the distance through which the boat moves in 20.0 s will be 85 m.

(c)Velocity at the end of that time will be 8.5 m/sec.

<h3>What is velocity?</h3>

The change of distance with respect to time is defined as speed. Speed is a scalar quantity. It is a time-based component. Its unit is m/sec.

Given data;

Forwad force acting on the boat,v₁ = 1,800-N

Resistive force acting on the boat,v₂ = 1,200-N

The acceleration of the boat,a

Mass of boat,m = 1,400-kg

Initial velocity of boat,u= 0 m/sec

Distance travelled by boat,S = ?

Time for the boat travels,t = 20.0 s

Final velocity,V = ? m/sec

The net force on the boat;

F = F₁ - F₂

F = 1800 N - 1200 N

F = 600 N

From the defination of force;

F= ma

a = F / m

a = 600 N / 1400 kg

a = 0.425 m/sec²

b)

The distance through which the boat moves is 20.0 s;

\rm x_f = x_ 0 + v_0 t + \frac{1}{2} at^2 \\\\ x_f  = \frac{1}{2}at^2 \\\\ x_f = 0+0 + \frac{1}{2} at^2 \\\\ x_f = \frac{1}{2}\times 0.425 \times (20 )^ 2 \\\\ x_f  = 85 \ m

c)

The velocity at the end of that time is found as;

\rm  v_f = v_ 0 + at \\\\ v_f =- 0+ at \\\\ v_f = 8.5 m/sec

Hence the acceleration of the boat, the distance through which the boat moves in 20.0 s, and velocity at the end of that time will be 0.425 m/sec²,85 m, and 8.5 m/sec.

What are advantages and disadvantages of using a solar cooker compared to other meanings of cookings?
drek231 [11]

The advantage of using a solar cooker is that it is Eco-friendly and the disadvantage is that it can be used only under certain conditions.

<h3><u>Explanation:</u></h3>

A solar cooker is used for cooking food without having to use electricity or gas. Instead, the appliance uses heat from the sun to cook food. It is used widely in by people who travel in remote areas or go on trips. But the appliance has limitations of its own too.

ADVANTAGES

  • Using it is friendly to the environment
  • It can be easily assembled without expert assistance
  • No compromise on the quality and taste of foo

DISADVANTAGES

  • Requires sun to function and prepare food
  • Cannot function in winters or monsoon when the sun isn't present
  • Does not retain heat as efficiently and quickly as compared to other cooking appliances

A sports car accelerates from rest for 5 seconds reaching a velocity of 23.0 m/s.
denis-greek [22]

Answer:

<h2>4.6 m/s²</h2>

Explanation:

The acceleration of an object given it's velocity and time taken can be found by using the formula

<h3>a =  \frac{v - u}{t}  \\</h3>

where

v is the final velocity

u is the initial velocity

t is the time taken

a is the acceleration

Since the body is from rest u = 0

From the question we have

a =  \frac{23 - 0}{5}  =  \frac{23}{5}  \\

We have the final answer as

<h3>4.6 m/s²</h3>

Hope this helps you
