Answer:
Explanation:
Momentum is the mass of a moving body times its velocity. It can be transferred from one object to another
In order to completely describe a velocity,
you need a speed and a direction.
Power = Net Force x velocity
Net force = driving force - force of resistance
Driving force = mass x acceleration
Acceleration = (final velocity - initial velocity) / time
Acceleration = (18 - 0) / 12 = 1.5 m/s²
Driving force = 1.5 x 10³ x 1.5
= 2250 N
Net force = 2250 - 400
= 1850
Power = 1850 x 18
= 3.33 x 10⁴ Watts
Answer:
200 N/m
20 rad/s
0.31415 seconds
3.18309 Hz
Explanation:
m = Mass of glider = 0.5 kg
x = Displacement of spring
F = Force on spring = 6 N
From Hooke's law we have relation

The spring constant is 200 N/m
Angular frequency is given by

The angular frequency is 20 rad/s
Frequency is given by

The frequency is 3.18309 Hz
Time period is given by

The time period is 0.31415 seconds
