Answer:
3.33 m/s²
Explanation:
If the acceleration is constant, it is equal to the average acceleration:
a = Δv / Δt
First, convert km/hr to m/s:
300 km/hr × (1 hr / 3600 s) × (1000 m/km) = 83.33 m/s
a = (83.33 m/s − 0 m/s) / 25 s
a = 3.33 m/s²
Answer:
impulse will be equal to 1.969 N-s
Explanation:
We have given mass of the golf ball m = 60.8 gram = 0.0608 kg
Horizontal speed of the ball is v = 32.4 m/sec
We have to find the impulse of the golf ball
We know that impulse is equal to momentum of the object
So we have to find the momentum of the object
Momentum of the object is equal to product of mass of the object and speed of the object
So
As momentum is equal to impulse so impulse will be equal to 1.969 N-s
Answer:
The acceleration of the proton is 2.823 x 10¹⁷ m/s²
The acceleration of the electron is 5.175 x 10²⁰ m/s²
Explanation:
Given;
distance between the electron and proton, r = 7 x 10⁻¹⁰ m
mass of proton, = 1.67 x 10⁻²⁷ kg
mass of electron, = 9.11 x 10⁻³¹ kg
The attractive force between the two charges is given by Coulomb's law;
where;
k is Coulomb's constant = 9 x 10⁹ Nm²/c²
Acceleration of proton is given by;
F = ma
Acceleration of the electron is given by;
None unless you wanna have carcinogens in your blood

The value is
Explanation:
From the question we are told that
The mass of the first lead sphere is
The mass of the second lead sphere is
The separation between masses is
Generally the gravitational force between each sphere is mathematically represented as
Here G is the gravitational constant with value
