Answer:
A ball is thrown in an arbitrary direction and a rocket moves through the sky after its engines have failed.
Explanation:
The concept applied is that of projectile motion which is the free fall for both then horizontal and vertical component of a constant velocity. it is also the motion of an object thrown under the influence of acceleration due to gravity.
The correct option are as follows ; A ball is thrown in an arbitrary direction and a rocket moves through the sky after its engines have failed.
For the first case ; A ball is thrown in an arbitrary direction ; after the ball must have been thrown, the projectile further moves in a curved path.
for the second case ; A rocket moves through the sky after its engines have failed ; the rocket also moves in a curved path under the influence of the acceleration due to gravity.
Answer:9.51 m/s
Explanation:
Given
Window is 4.35 m above ground
time taken=1.2 s
Let u be the initial velocity of keys
where s=distance traveled
u=initial velocity
t=time taken
g=acceleration due to gravity
(b)velocity of keys just before they were caught
v=u+at
v=-2.26 m/s
Here negative sign indicates downward motion of keys
All of the above, work is a measurement of energy transfer, in Joules.
Potential energy = Joules
Kinetic energy = Joules
The key thing here is that anything having to do with just energy or energy transfer is measured in joules.
