Given that,
Acceleration, a = 9.71 m/s²
Force, F = 5050 N
mass, m = ?
Since, we know that
F=ma
m= F/a
m= 5050/9.71
m= 520.08 kg
The mass of hi car is 520.08 kilograms.
Answer:
22.22m/s
Explanation:
The momentum before a collision = momentum after collision so...
work out the momentum of the first object (the bullet)
its p = mv
0.04 kg × 300 m/s = 0.54 kg × v
rearrange this to find v which is 0.04 x 300 = 12
so 12 = 0.54 x v
12/0.5 = v
v = 22.22m/s
hope this helps!
Answer:
A. 
B. P ≈ 0
Explanation:
In order to calculate the magnetic field strength we have to use the magnetic field strength of a straight wire.
(eq. I)
B = magnetic field strength at distance d
I = current (A)
mi = represented by the greek letter μ, represents the permeability of the free space, which is: 4 × π 10^(-7) T m/A
d = distance from the wire
By replacing the values in eq I, we have the following:
(eq II)
The earth magnetic field in the surface variates from 25 to 65 microteslas. Thus:
P = Percentage from the wires/percentage of the earth
∵
∴
P ≈ 0
Answer:
True
Explanation:
an object in motion stays in motion unless acted upon by another force
Momentum is a product of mass and the velocity of a body. The initial momentum is always equal to the final momentum during collisions between two bodies.
Therefore; M1U1 +M2U2 = M1V1+ M2V2, where m1 is the mass of tracey and m2 is the mass of jonas, while u is the initial velocity and v is the final velocity.
(32 ×0)+ (45×0) = (32 × v1) + (45 × 0.50)
0 = 32V1 + 22.5
32 V1 = -22.5
V1 = - 0.703 ( negative indicates difference in direction)
There, Tracey's speed will be 0.703 m/s
