A volleyball is hit and experiences a net

Physics
1 answer:
Ierofanga [76]3 years ago
6 0

Answer: 0.25 kg

Explanation:

Given that,

net force = 2 N

acceleration of volleyball = 8 m/s

mass of the volleyball = ?

According to the Newton 2nd law of motion, net force depends on the mass of the object and acceleration by which it moves.

i.e Net force = mass x acceleration

2N = mass x 8m/s²

Mass = 2N / 8m/s²

Mass = 0.25 kg

Thus, the mass of the volleyball is 0.25 kg

Anna71 [15]

(D) The gravitational force between the astronaut and the asteroid.

Reason :

All the other forces given in the options, except (D), doesn't account for the motion of the astronaut. They are the forces that act between nucleons or atoms and neither of them accounts for an objects motion.

A particle starts from rest and has an acceleration function 5 − 10t m/s2 . (a) What is the velocity function? (b) What is the p
frez [133]

Explanation:

It is given that,

A particle starts from rest and has an acceleration function as :

a(t)=(5-10t)\ m/s^2

(a) Since, a=\dfrac{dv}{dt}

v = velocity

dv=a.dt

v=\int(a.dt)

v=\int(5-10t)(dt)

v=5t-\dfrac{10t^2}{2}=5t-5t^2

(b) v=\dfrac{dx}{dt}

x = position

x=\int v.dt

x=\int (5t-5t^2)dt

x=\dfrac{5}{2}t^2-\dfrac{5}{3}t^3

(c) Velocity function is given by :

v=5t-5t^2

5t-5t^2=0

t = 1 seconds

So, at t = 1 second the velocity of the particle is zero.
