Answer:

Acceleration = 0.2m/s²

Explanation:

Given the following data;

Mass = 1000kg

Force = 200N

To find acceleration;

Force is given by the multiplication of mass and acceleration.

Mathematically, Force is;

F = ma

Where;

F represents force.

m represents the mass of an object.

a represents acceleration.

Making acceleration (a) the subject, we have;

Acceleration (a) = \frac{F}{m}

Substituting into the equation;

Acceleration (a) = \frac{200}{1000}

Acceleration = 0.2m/s²

Answer:

1.The force required to stop the shopping cart is, F = 12.25 N

Explanation:

Given data,

The mass of the shopping cart, m = 7 kg

The initial velocity of the shopping cart, u = 3.5 m/s

The final velocity of the shopping cart, v = 0 m/s

The time period of acceleration, t = 2 s

The change in momentum of the cart,

                                      p = m(u - v)

                                         = 7 (3.5 - 0)

                                         = 24.5 kg m/s

The force is defined as the rate of change of momentum. To stop the shopping cart, the force required is given by the formula

                                           F = p / t

                                               = 24.5 / 2

                                               = 12.25 N

Hence, the force required to stop the shopping cart is, F = 12.25 N

2.

We have: F = m × v/t

Here, m = 8500 Kg

v = 20 m/s

t = 10 s

Substitute their values into the expression,  

F = 8500 × 20/10

F = 8500 × 2

F = 17000 N

In short, final answer would be 17000 N

Hope this helps!!

to lift a load to roof, you apply 21 n of force to a pulley. the pulley applies 21 n of force to the load. what is the mechanica
MariettaO [177]

Answer:

The mechanical advantage of the pulley is 1.

Explanation:

The mechanical advantage of the pulley is given as

MA=\frac{F}{f}

Here, MA is represent for the mechanical advantage of the pulley, F is load for lift and f applied force.

Given F =21 N and f= 21 N.

Substitute the given values, we get

MA=\frac{21N}{21N}

MA = 1.

Thus, the mechanical advantage of the pulley is 1.

Explain how we use a spectrometer to help us determine what stars and planets are made of?
BaLLatris [955]
We use a spectrometer to help us determine what stars and planets are made of by passing a light through various chemical elements, different spectral patterns are created. By matching those patterns up to patterns generated in a laboratory environment we can tell what the composition of a distant star or planet is.
