Answer:
Explanation:
Assuming motion of equation of SHM as
where,
t=time
thus velocity at any Point x is given by
when speed is 50 % of its maximum value
(b)When Potential Energy is 50 % of total energy
Total Energy
potential energy at any x is given by
Answer:
θ = 33°
Explanation:
Here, we can use the formula for the total time of flight of a projectile to calculate the launch angle of frog:
where,
θ = launch angle = ?
T = Total time of flight = 0.6 s
g = acceleration due to gravity = 9.81 m/s²
u = launch speed = 5.4 m/s
Therefore,
<u>θ = 33°</u>
If two charges are moved so that the distance between them is reduced
by half, then the forces between them become 4 times as strong.
here our distance is given with respect to ticket booth
initial distance is given 50 m from the booth
So our initial position is
now after this finally we reach at final position
now change in position is given as
<em>so change in position is 45 m in magnitude and since we are coming closer to the booth so its coming negative in sign</em>
In physics, the principle of conservation of momentum states that when you have an isolated system with no external forces, the initial total momentum of objects before a collision equals the final total momentum of the objects after the collision.
