How much does a 200 kg car weigh?

1 answer:

adoni [48]3 years ago

5 0

These weights are minus the transmission which can push the car engine weight to around 600 pounds. While most formula ones cars are extremely fast the engines used are lightweight and weigh 100 kg or 210 pounds.

Two hockey players have a total momentum of +200 kg x m/s before a collision (+ is to the right). After the collision, they move

Juliette [100K]

Total momentum after the collision: +200 kg m/s to the right

Explanation:

We can answer this question by using the law of conservation of momentum, which states that for an isolated system (=no external forces acting on the system), the total momentum is conserved.

Mathematically,

$p_i=p_f$

where

$p_i$ is the total momentum before the collision

$p_f$ is the total momentum after the collision

In this problem, the system consists of two hockey players. Before the collision, their total momentum is

$p_i = +200 kg m/s$ (to the right)

Therefore, according to the law of conservation of momentum, their total momentum after the collision must be the same:

$p_f = +200 kg m/s$

And given that the sign is +, the direction is still the same, therefore to the right.

A 300W hot plate produces 45,000 J of thermal energy while operating for 2 min. What is the efficiency of this devide? it need t

Gekata [30.6K]

Answer:

Explanation: P = 300 W and t = 2 min = 120 s

Energy Q = Pt = 300 W · 120 s = 36 000 J.

Thus, plate can not produce 45 000 J heat.

Two coils of wire are placed close together. Initially, a current of 3.04 A exists in one of the coils, but there is no current

Alchen [17]

Answer:

$M=0.0247H$

Explanation:

Given data

$V_{voltage}=4.29V\\I_{current}=3.04A\\t_{time}=1.75*10^{-2}s$

To find

Mutual inductance of the two-coil system

Solution

The mutual inductance given as:

M= (-VΔt)/ΔI

Substitute the given values

So

$M=-\frac{4.29V*1.75*10^{-2}s}{(0-3.04A)}\\ M=0.0247H$

If Bert the Bat travels East at 200 meters in 10 seconds, what is his velocity?

dexar [7]

Answer:

20m/s due east

Explanation:

Given parameters:

Displacement eastward = 200m

Time = 10s

Unknown:

Velocity = ?

Solution:

Velocity is the displacement divided by time;

Velocity = $\frac{displacement}{time}$

Velocity = $\frac{200}{10}$ = 20m/s due east

A 290 gg bird flying along at 6.2 m/sm/s sees a 9.0 gg insect heading straight toward it with a speed of 34 m/sm/s (as measured

Murrr4er [49]

Answer:

The bird's speed immediately after swallowing is 4.98 m/s.

Explanation:

Given that,

Mass of bird = 290 g

Speed = 6.2 m/s

Mass of sees = 9.0 g

Speed = 34 m/s

We need to calculate the bird's speed immediately after swallowing

Using conservation of momentum

$m_{1}v_{1}+m_{2}v_{2}=(m_{1}+m_{2})v_{3}$

Put the value into the formula

$0.290\times6.2+0.009\times(-34)=(0.290+0.009)\times v_{3}$

$v_{3}=\dfrac{0.290\times6.2-0.009\times34}{(0.290+0.009)}$

$v_{3}=4.98\ m/s$

Hence, The bird's speed immediately after swallowing is 4.98 m/s.
