Answer:
Coefficient of friction is the ratio of friction force to normal force.
μ = F/N
The weight of the car in the picture of the computer screen is 9,800 Newton's.
Answer:4.04 m
Explanation:
mass of athlete
initial speed
To get the maximum height h of Athlete we conserve energy i.e.
Kinetic Energy of Athlete=Potential energy gained by athlete
(b)Speed at half of maximum height
Considering v be the velocity at half of maximum height
conserving Energy we can write
(as )
thus
So Athlete interact with the gravitational Field of Earth
Answer:
Mass of B is 10 kg
Explanation:
M1v1a + m2v1b = m1v2a + m2v2b
Let m2 = x
5*20 + x10 = 5*10 + x15
100 + x10 = 50 + x15
50 = x5
X= 10
Mass of B is 10 kg
M1 = mass of A
V1a = initial velocity of A
V2a = final velocity of A
M2 = mass of B
V1b = initial velocity of B
V2b = final velocity of B
