Aspring-mass system is undergoing simple harmonic motion of amplitude 2.2 cm and angular frequency 10.4 s−1. the magnitude of the maximum acceleration of the mass as it oscillates back and forth is a spring-mass system is undergoing simple harmonic motion of amplitude 2.2 and angular frequency 10.4 . the magnitude of the maximum acceleration of the mass as it oscillates back and forth is a. 0.00 m/s2. b. 0.21 m/s2. c. 2.38 m/s2. d. 15.0 m/s2.

the chart show the masses and velocities of two colliding objects that stick together after a collision.

according to the law of conservation of momentum, the momentum of the object after the collision is  

answer

1,500

kg • m/s.

initial speed when it is dropped is 150 ft/s

now at the same moment the acceleration due to gravity is perpendicular to its velocity

so as we know that

now we have centripetal acceleration a = 32 ft/s^2 as its perpendicular to velocity

while tangential acceleration at the same moment will be zero

so

now radius of curvature is given as

so the radius of curvature just after it is dropped is 703.125 ft

3. dark matter

empty space could also be a simple vacuum

490 n

f=125n a=2.5m/s2
