Answer:
10 m
Explanation:
Weight = 10 N
mg = 10
m = 10 / 10 = 1 kg
g = 10 m/s^2
Initial mechanical energy = 40 J
Final mechanical energy = 140 J
change in total energy = 140 J – 40 J = 100 J
At the maximum vertical height, the velocity = 0 m/s
So,it has only potential energy at maximum height
P = m x g x h
100 = 1 x 10 x h
h = 10 m
Answer:
20m/s
Explanation:
Given parameters:
Distance of throw = 50m
Time = 3s
Unknown:
Average speed = ?
Solution:
Average speed is distance divided by time;
Average speed =
Insert the parameters and solve;
Average speed = = 16.66667m/s = 20m/s
Answer:
The net force acting on an object is proportional to the acceleration of that object with respect to an inertial frame of reference. The constant of proportionality in this, Newton's second law, is the classical mass of the object.
