When a cricket ball is thrown vertically upwards it reaches a maximum height of 5 Metre What was the initial speed of the world?
Note − The initial velocity was negative i.e. −10 m/s, as it was velocity against gravity because the ball was thrown upwards. This can be neglected. t (time) = ? Since , time cannot be negative, so,the required answer is s .
When a cricket ball is thrown vertically upwards it reaches a maximum height of 5m find the initial speed of the ball?
Hence, the initial velocity of the ball was 10 m/s. Was this answer helpful?
When a ball is thrown vertically upward with velocity v not?
Here, in this type of question if the object is thrown vertically upward and it reaches maximum height then at that height velocity becomes zero. Thus, in the formula we cannot use the final velocity because it’s already zero.
When a ball is thrown upwards its total energy?
Answer: When the ball is thrown upward its total energy remains conserved. Explanation: Since, in this situation the potential energy increases and the kinetic energy decreases.
When he throws the ball vertically upwards what will happen to the energy stored in it?
Hence, total energy will remain constant.
At what point the potential energy is maximum when a ball thrown upward?
At any point of time a body vertically thrown upward has 2 types of energy- kinetic (due to speed) and potential energy (due to position). At the initial position (at the moment of throwing) its kinetic energy is maximum and potential energy is zero.
Where is the energy of a vertically projected body maximum?
When a body is vertically projected, its velocity decreases to zero. At the maximum height the velocity is zero and hence the kinetic energy is zero….
When a ball is thrown vertically upwards the gravitational potential energy of the ball * 1 point?
Answer. PE= m×g×h, which shows that potential energy is directly proportional to height, hence as height increases, potential energy increases.
When a ball is thrown upward It reaches a maximum height and then descends what happens to the potential energy during the motion *?
During its upward journey the velocity decreases and hence kinetic energy also decreases. To compensate the decrease in kinetic energy the potential energy increases to the extent at that instant. Hence at that top when velocity is zero, kinetic energy is also zero and potential energy is maximum.
What is the total energy of a ball the moment it is thrown from a window 5.5 meters from the ground if the velocity of the ball is 10 meters second when it leaves the window assume the ball has no potential energy when it is on the ground the mass of the ball is 50 g 1 point 5.2 J?
Total energy of the ball the moment it throws the window = ( 2.695 + 2.5 ) = 5.195 joules.
What is the relationship between speed and Ke?
This equation reveals that the kinetic energy of an object is directly proportional to the square of its speed. That means that for a twofold increase in speed, the kinetic energy will increase by a factor of four. For a threefold increase in speed, the kinetic energy will increase by a factor of nine.
Can kinetic energy increase if net force is zero?
Net Force on System Not Equal Zero, but GPE increases and no change in Kinetic Energy. However, the net force on the book is zero. So, by Newton’s Second Law, the system should accelerate and there should be a change in kinetic energy and thus work will be done on the system.
