Answer:
The acceleration is 5 m/s2.
Explanation:
We calculate the acceleration, with the data of mass and force, through the formula:
F= m x a ---> a= F/m
a= 200 N/40 kg 1N= 1 kg x m/s2
a= 200 kg x m/s2/ 40 kg
<em>a= 5 m/s2</em>
A particle moving at speed 0.24 c has momentum P₀. The speed of the particle is increased to 0.68 c then its momentum would be 2.85P₀.
Momentum is the result of a particle's mass and velocity. Being a vector quantity, momentum possesses both magnitude and direction.
Mathematically the formula of the momentum is
P = mv
where P is the momentum of the particle
m is the mass of the particle
v is the velocity by which the particle is moving
As mentioned in the question when the particle is moving with 0.24c velocity it has a momentum of P₀
P₀ = m*(0.24c)
If the speed of the particle is increased to 0.68 c the momentum would be
P=m*(0.68c)
by dividing the second equation from the first one
P₀/P = 0.24c/0.68c
P₀/P = 0.35
P =2.85P₀

Answer:
f - f '= 6.18*10^11 Hz
Explanation:
The change in frequency is given by:
f': observed frequency
f: source frequency = 6.17*10^14 Hz
v: speed of the source = 3.01*10^55 m/s
c: speed of light = 3*10^8 m/s
By replacing all these values you obtain:
hence, the change in frequency f-f' will be:
f - f '= 6.18*10^11 Hz
