A. Discovering a quick way to handle a new problem
Answer:
option (c)
Explanation:
According to the newton's third law, for every action there is an equal and opposite reaction.
As the astronaut throw the tool away from the shuttle, it means the action force is in the direction away from the shuttle and according to Newton's third law, the reaction force is getting in the direction of shuttle.
Answer:
The bicyclist's acceleration is 2.2m/s^2
Explanation:
Given
---- Initial Velocity
---- Final Velocity
---- Time
Required
Determine the acceleration
This will be solved using the first equation of motion
Substitute values for v, u and a
Collect Like Terms
Solve for a
---- (approximated)
<em>Hence, the bicyclist's acceleration is 2.2m/s^2</em>
I think it’s false. The second law states that the acceleration of an object is dependent upon two variables - the net force acting upon the object and then mass of the object.
