Answer:
No there is no displacement observed so no work done
Answer:
No.
Explanation:
Because the acceleration of falling objects is constant and is not affected by mass
Answer:
Acceleration due to gravity 9.8 m/s^2
Explanation:
When an object drops down towards earth from certain height than it comes down with an acceleration of 9.8 m/s^2 which is constant throughout the dropping until the falling objects hits the ground and coming to rest.
Answer:
Cold
Explanation:
Im pretty sure im sorry if I am wrong
Answer:
28.2 m/s
Explanation:
The range of a projectile launched from the ground is given by:

where
v is the initial speed
g = 9.8 m/s^2 is the acceleration of gravity
is the angle at which the projectile is thrown
In this problem we have
d = 81.1 m is the range
is the angle
Solving for v, we find the speed of the projectile:
