A 2.9 gram bullet is shot into a tree stump. It enters at a velocity of 304 m/sec and comes to rest after having penetrated the

Helga [31]

First convert grams to kilograms (so that the answer will be N) 1000g=1kg so 2.9g=.0029kg.

To solve for force we use the equation F=ma, so we need to find acceleration (a) .Next use the equation a=Δv/Δt. Δt is given as being .00043 seconds. Δv is the difference in velocities - final minus initial (this is important to discern the direction of the force vector); 0-304=-304. Now plugin and solve for a. The result is -706976.7442 m/s², or -710000 m/s² if you are using significant figures.

Now use the values for mass and acceleration to solve for force. F=ma=-2050.232558N or F=- 2100N (if you are using significant figures).

A force of 40N is applied to a 28 g mass, what is the acceleration? (round to the hundredths place)

Leno4ka [110]

Answer:

1428.6m/s²

Explanation:

Given parameters:

Force applied on the body = 40N

Mass of the body = 28g

1000g = 1kg

28g will therefore be 0.028kg

Unknown:

Acceleration = ?

Solution:

To solve this problem, we use the expression derived from Newton's second law of motion.

Force = mass x acceleration

Insert the parameters and solve;

40 = 0.028 x acceleration

Acceleration = $\frac{40}{0.028}$ = 1428.6m/s²

A 10.0 m wire is hung from a high ceiling and held tightly below

yan [13]

Answer:

5 m

Explanation:

Speed of waves is as the product of frequency and wavelength hence expressed as s=fw where f is the frequency of waves in Hz, s is the speed in m/s and w is wavelength in meters.

Making w the subject of the formula then

$w=\frac {s}{f}$

Substituting 335 m/s for s and 67 Hz for f then the wavelength is

$w=\frac {335}{67}=5m$

Wavelength is the distance between successive crests. Since the string is 10m, wavelengths of 5m each will be 2 and the crests will be 3.
