Answer:
Weight on Jupiter will be equal to 2940 N
Explanation:
We have given given acceleration due to gravity on Jupiter is 3 times of acceleration due to gravity on earth
Acceleration due to gravity on earth
So acceleration due to gravity on Jupiter =
Mass is given m = 100 kg
We have to find the weight
Weight is equal to W = mg, here m is mass and a is acceleration
So weight
A) The kinetic energy of an object is given by:
where m is the mass of the object, and v its speed. For the lion in our problem, m=45 kg and v=14.2 m/s, so its kinetic energy is
b) the increase in gravitational potential energy of the lion is given by:
where g is the gravitational acceleration, and
is the increase in altitude of the lion. In this problem, 
, so the increase in gravitational potential energy is
c) When the fox reaches the top of the tree, its gravitational potential energy is
As it jumps, its kinetic energy is
So the total mechanical energy of the fox as it jumps is
where m is the mass of the object, and v its speed. For the lion in our problem, m=45 kg and v=14.2 m/s, so its kinetic energy is
b) the increase in gravitational potential energy of the lion is given by:
where g is the gravitational acceleration, and
c) When the fox reaches the top of the tree, its gravitational potential energy is
As it jumps, its kinetic energy is
So the total mechanical energy of the fox as it jumps is
Answer:
The angular acceleration is
Explanation:
Given that,
Angular velocity,
Angular velocity,
Time t = 10.0 sec
We need to calculate the angular acceleration
Using formula of angular acceleration
Now, we change the angular velocity in rad/s.
Hence, The angular acceleration is
