Answer:
Explanation:
As it’s difficult to catch it from up.
Gravitational force will pull us when we jump.
If gravity was not there, he could catch the ball. But he will float in the sky after that.
That’s the answer
Answer:
Explanation:
The centripetal acceleration is given by:
Here v is the linear speed and r is the radius of the circular motion. v is defined as the distance traveled to make one revolution (
) divided into the time takes to make one revolution, that is, the period (T).
Replacing (2) in (1) and replacing the given values:
Answer:
39975kgm/s due east
Explanation:
Given parameters:
Mass of the blimp = 533kg
Velocity = +75m/s due east
Unknown:
Momentum of the body = ?
Solution:
The momentum of a body is the amount of motion it posses.
Momentum is the product of mass and velocity;
Momentum = mass x velocity
Insert the parameters and solve;
Momentum = 533 x 75 = 39975kgm/s
The momentum of the body is 39975kgm/s due east
The key projectile motion is that gravity allows downward only
