So you can use the equation force = mass x acceleration to do 2 x 5 to get 10 N
Explanation:
The strength of the gravitational force between two objects depends on two factors, mass and distance. the force of gravity the masses exert on each other. ... increases, the force of gravity decreases. If the distance is doubled, the force of gravity is one-fourth as strong as before.
Answer:
The maximum height of the ball is 2 m.
Explanation:
Given that,
Mass of ball = 50 g
Height = 1.0 m
Angle = 30°
The equation is
We need to calculate the velocity
Using conservation of energy
Here, ball at rest so initial kinetic energy is zero and at the bottom the potential energy is zero
Put the value into the formula
Put the value into the formula
We need to calculate the maximum height of the ball
Using again conservation of energy
Here, h = y highest point
Put the value into the formula
Put the value of y in the given equation
Hence, The maximum height of the ball is 2 m.
Answer:
K = 0.076 J
Explanation:
The height of the target, h = 0.860 m
The mass of the steel ball, m = 0.0120 kg
Distance moved, d = 1.50 m
We need to find the kinetic energy (in joules) of the target ball just after it is struck. Let t is the time taken by the ball to reach the ground.
Put all the values,
The velocity of the ball is :
The kinetic energy of the ball is :
So, the required kinetic energy is 0.076 J.
