A hockey player uses a 400- gram stick to apply 50 newtons of force to a 170-gram puck, causing a momentum of change 5kg x m/s.
What is the impulse experienced by the hockey puck?
1 answer:
Answer: 5 N•s
Explanation:
An impulse will result in a change of momentum.
If the momentum changed 5 kg•m/s, you can be certain that an impulse of 5 N•s has been applied.
The units for Impulse and momentum are identical
kg•m/s = N•s
if we divide each side by s
kg•m/s/s = N•s/s
kg•m/s² = N
which is probably familiar already

Answer:
The heat causes the molecules on rubbing surfaces to move faster and have more energy.
Cups
teaspoon
tablespoon
liters
milliliters
gallons
pints
tons
inches
Explanation:
v = wavelength x frequency
330 = 5 . 10-² m x f
f = 6600 Hz
the frequency that human can hear is about 20 Hz - 20000 Hz
so human can hear the note.
Answer:
Explanation:
given data
Radius of sphere 3.0 cm
charge Q = 2.0 m C
We know that maximum electric field is given as
electric field inside the sphere can be determine by using below relation
Y - yo = Vo*t - g * (t^2) / 2
Vo = - 9.0 m/s
t = 0.50 s
=> y - yo = -9.0 m/s * 0.5 s - 9.8 m/s^2 * (0.5s)^2 / 2 = - 4.5m - 1.225m = - 5.725 m.
Answer: option c) - 5.7
