Answer:
When two objects collide, a force is exerted on each object. The two forces are in opposite directions but the same strength. Even though the force on each object in a collision is the same strength, the objects will have different velocity changes if their masses are different.

Answer:
Explanation:
From the question we are told that
Distance b/w plate
P_1 Potential at 7.35
Generally the equation for electric field at a distance is mathematically given as
Answer:
0.5 m/s
Explanation:
From Newton's Third law of motion,
Momentum of the cannon = momentum of the flatcar.
mv = MV........................ Equation 1
Where m = mass of the cannon, v = velocity of the cannon, M = mass of the flatcar, V = Velocity of the flat car.
make V the subject of the equation
V = mv/M................... Equation 2
Given: m = 10 kg, v = 50 m/s, M = 1000 kg
Substitute into equation 2
V = 10×50/1000
V = 500/1000
V = 0.5 m/s
Hence the speed of the flatcar = 0.5 m/s
Answer:
a) 6.25 m/s
b) f = 832 N
Explanation:
given data:
mass of child = 36 kg
length 2.94 m
tension = 416 N
For part (A), we need to add the forces in normal direction F(n),
where T is tension
m is mass, g = 9.81 m/s^2, and
a is acceleration is given as.
where v is speed
r is the radius.
v = 6.25m/s
Part B)
F = 2*(416)
F = 832 N
