Question 1
A particle moves in one dimension with position x(t) = t³ − 6t² + 9t (meters, t in seconds). At what times is the particle momentarily at rest?
Correct Answer:
t = 1 s and t = 3 s
Question 2
A block of mass m slides down a frictionless inclined plane of angle θ. What is the acceleration of the block along the plane?
Correct Answer:
g sin θ
Question 3
A 2 kg block compresses a spring (k = 800 N/m) by 0.10 m and is then released from rest on a frictionless surface. What is the speed of the block when it leaves the spring?
Correct Answer:
2.0 m/s
Question 4
A uniform rigid rod of mass M and length L is pivoted at one end and held horizontal. When released, what is the angular acceleration immediately after release?
Correct Answer:
3g/(2L)
Question 5
Two point masses m₁ = 3 kg and m₂ = 1 kg undergo a perfectly inelastic collision. Before the collision, m₁ moves at 4 m/s and m₂ is at rest. What is the kinetic energy lost in the collision?
Correct Answer:
6 J
