Answer:

magnitude of angular momentum of the coconut after t = 1 s is

L = 1930.4 kg m^2/s

Explanation:

Since it is dropped at the instant when it is at overhead position

so we will have

v_x = 6.61 m/s

now vertical speed of the coconut after t = 1 s

v_y = 0 - gt

v_y = -9.8 m/s

now its displacement in x direction is given as

x = 6.61 (1) = 6.61 m

height of the coconut after t = 1 s

y = 21.4 - \frac{1}{2}gt^2

y = 21.4 - \frac{1}{2}(9.81)(1^2)

y = 16.5 m

now angular momentum is given as

L = \vec r \times m\vec v

now we have

L = (6.61 \hat i + 16.5 \hat j)\times (11.1)(6.61 \hat i - 9.81\hat j)

L = -719.8 \hat k - 1210.6\hat k

so magnitude of angular momentum of the coconut after t = 1 s is

L = 1930.4 kg m^2/s

A well-thrown ball is caught in a well-padded mitt. If the deceleration of the ball is 2.10×104 m/s2 , and 1.85 ms (1 ms = 10−3
ankoles [38]

Answer:

u = - 38.85 m/s^-1

Explanation:

given data:

acceleration = 2.10*10^4 m/s^2

time = 1.85*10^{-3} s

final velocity = 0 m/s

from equation of motion we have following relation

v = u +at

0 =  u + 2.10*10^4 *1.85*10^{-3}

0 = u + (21 *1.85)

0 = u + 38.85

u = - 38.85 m/s^-1

negative sign indicate that the ball bounce in opposite directon

When are magnets attracted and when are they repelled.
vova2212 [387]
Magnets are attracted when each of the different sides, most commonly known as "North" and "South", are facing each other. They repel when North and North, or South and South are facing each other.

The velocity of a body is given by the equation v= a + bx, where 'x' is displacement. The unit of b is .......
valina [46]

Answer:

s^ -1    ( or    1/sec)

Explanation:

Velocity is given in units of displacement / sec

like feet /sec   or   m/sec    

so b would have units of   s^-1

(or perhaps a more general term would be   time^-1)

What's the difference and similarity between O2 and 2 O ?
nasty-shy [4]
O2 refers to two oxygen atoms bonded together, while 2 O refers to two oxygen atoms that are not bonded to each other. They both have two oxygen atoms, but in O2, the oxygen atoms are bonded, while in 2O, the atoms are not.
