Answer:

option (c)

Explanation:

The velocity of the oscillating body is zero when it is at its maximum displacement position from its mean position.

So, when the spring is fully stretched, means at maximum displacement the velocity is zero.

Nataly [62]

Your answer is C)

a)t=2.78 sec

b)R=835.03 m

c)

Explanation:

Given that

h= 38 m

u=300 m/s

here given that

The finally y=0

So

t=2.78 sec

The horizontal distance,R

R= u x t

R=300 x 2.78

R=835.03 m

A horizontal platform in the shape of a circular disk rotates on a frictionless bearing about a vertical axle through the center
uranmaximum [27]

Answer:

4.36 rad/s

Explanation:

Radius of platform r = 2.97 m

rotational inertia I = 358 kg·m^2

Initial angular speed w = 1.96 rad/s

Mass of student m = 69.5 kg

Rotational inertia of student at the rim = mr^2 = 69.5 x 2.97^2 = 613.05 kg.m^2

Therefore initial rotational momentum of system = w( Ip + Is)

= 1.96 x (358 + 613.05)

= 1903.258 kg.rad.m^2/s

When she walks to a radius of 1.06 m

I = mr^2 = 69.5 x 1.06^2 = 78.09 kg·m^2

Rotational momentuem of system = w(358 + 78.09) = 436.09w

Due to conservation of momentum, we equate both momenta

436.09w = 1903.258

w = 4.36 rad/s

Consider the two vectors A(with arrow above)=5i-3j and B(with arrow above)=-i-2j
KatRina [158]
<span>
A= 5 i − 3 J and B = −i − 6 j 

A+ B 
=5 i − 3 j −i − 6 j = 4 i - 9 j ---answer 

A - B 
= 5 i − 3 j + i + 6 j = 6 i + 3j ---answer 

|A+B| 
= sq root [ 16 + 81] = 9.848 ---answer 

|A - B| 
= sq root [ 36 + 9] = 6.708 ---answer 

directions of A+ B 
= tan (-1) -9 /4 = - 66 deg --answer 

direction of A- B 
= tan (-1) 3 /6 = 26.56 deg --answer</span>

Calculate the total rotational kinetic energy of the molecules in 1.00 mol of a diatomic gas at 300 K.
AURORKA [14]

Answer:

= 2.49 × 10³J

Explanation:

Total rotational kinetic energy K = nRT

R = 8.134 J/mol.K

n = 1 mol

T = 300 K

K  = 1 × 8.314 × 300

=  2.49 × 10³J
