The appropriate response is the revolution of the Earth around the Sun. For instance, the Earth finishes one turn about its hub about at regular intervals, yet it finishes one revolution around the Sun about each 365 days. Anyway, the fundamental motivation behind why the planets spin around, or circle, the Sun, is that the gravity of the Sun keeps them in their circles.
If the lens is convex image cannot be virtual
Take 10m/s^2 for the gravitational acceleration, as we know this is a free fall, we can use the equation: d=1/2*g*t^2
Substitute g=10m/s^2, t=5s, d=125m
Answer:
t = 2.55 s
Explanation:
Given that,
Height from which the baseball is thrown, h = 155 m
Initial velocity of the baseball, u = -25 m/s
We need to find the time taken by it to reach the ground. Let the time is t. Using equation of kinematics to find it as follows:
So, it will take 2.55 seconds to reach the ground.
