A block of mass 500 g is attached to a horizontal spring, whose force constant is 25.0 N/m . The block is undergoing simple harm

onic motion with an amplitude of 6.00 cm . At t=0 the block is 4.00 cm to the left of its equilibrium position and is moving to the right. At what time t1 will it first reach the limit of its motion to the right?

Answer:

t = 0.325343 sec

Explanation:

given

mass of block(m) = 500 g

force constant  (k) = 25.0 N/m

we know simple harmonic motion equation as

y = A sin (ωt + Φ)

 where  Φ = sin^{-1} (-4/6)

so we get

Φ = - 0.729727656 rad  

and we know

\omega  = \sqrt{\frac{k}{m}

y = A sin (t\sqrt\frac{k}{m} - 0.729727656)

now substitute the values we get as

y = 0.06 m

0.06 = 0.06 sin (t\sqrt(\frac{25}{0.5}) - 0.729727656)

(t\frac{25}{0.5} - 0.729727656) = \frac{\pi}{2}

on solving these equation we get

t = 0.325343 sec

Speedy Sue, driving at 34.0 m/s, enters a one-lane tunnel. She then observes a slow-moving van 160 m ahead traveling at 5.20 m/s
Zielflug [23.3K]

Answer:

there will be collision

Explanation:

v_{s} =  speed of sue = 34 m/s

v_{v} = speed of van = 5.20 m/s

v_{sv} = speed of sue relative to van  = v_{s} - v_{v} = 34 - 5.20 = 28.8 m/s

d_{s} = stopping distance after brakes are applied

D = distance between sue and van = 160 m

v_{f} = final speed of sue = 0 m/s

a = acceleration = - 1.80 m/s²

Using the kinematics equation

v_{f}^{2} = v_{o}^{2} + 2 a d_{s}

0^{2} = 28.8^{2} + 2 (1.80) d_{s}

d_{s} = 230.4 m

Since  d_{s} < D

hence there will be collision

Intense temperature and pressure of regional metamorphism

Explanation:

The process that cause the formation of the Vishnu Schist is the intense temperature and pressure as a result of regional metamorphism.

  • Regional metamorphism is an extensive metamorphism of an area as a result of temperature and pressure changes.
  • The schist is a foliated metamorphic rock usually found in areas of moderate to high grade temperature and pressure.
  • The Vishnu schist must have been metamorphosed before the new sediments were deposited on top.
