Answer:
E. downward and constant
Explanation:
Freefall is a special case of motion with constant acceleration because the acceleration due to gravity is always constant and downward. This is true even when an object is thrown upward or has zero velocity.
For example, when a ball is thrown up in the air, the ball's velocity is initially upward. Since gravity pulls the object toward the earth with a constant acceleration ggg, the magnitude of velocity decreases as the ball approaches maximum height. At the highest point in its trajectory, the ball has zero velocity, and the magnitude of velocity increases again as the ball falls back toward the earth.
Answer:
d = 13.7 m
Explanation:
When block is moving upwards along the inclined plane
then the block is decelerated due to gravity as well as due to friction and speed of the block by which it is projected upwards is given
deceleration caused to the block due to net force opposite to the motion is given as
since block is sliding on the inclined plane
so here we can say that the coefficient of the friction must be kinetic friction here
now for finding the distance upto which it will stop is given as
1) Answer:
98 N
Explanation:
The weight of an object is given by:
where m is the mass of the object and g is the gravitational acceleration. In this case, m=10 kg, therefore the weight of the lemur is
2) Answer:
87 N
Explanation:
The value of g at the International Space Station is . Therefore, the weight of the lemur on the Space Station will be
