As we can see here the lever has two forces at two ends
1. 300 N
2. 200 N
now we need to find the Torque on the lever about the fulcrum
so we will have
1. clockwise torque due to force at right end is
2. counterclockwise torque due to force at left end
so as per above calculations we can see that net torque on the lever is clockwise as it has more torque in clockwise direction
so <u>it will rotate clockwise</u>
PE equals KE when KE is 50%.
Like below:
E = PE + KE
E = 50 + 50
E = 100.
Remember, both KE and PE always have to add up to 100 so that is why PE is equal to KE when KE is 50% of energy.
Hope I helped. :)
Huhhhh this is confusing ummm hello I guess
Answer: The final Velocity, V, of the car is 7.9m/s
Explanation:
Given the following :
Toy car starts from rest, therefore,
Initial Velocity (u) = 0
Acceleration (a) = 1.5m/s^2 E for time, t = 5.25s
Final velocity (V) of the car =?
Using the motion equation:
v = u + at
Where v = final Velocity
u = Initial Velocity
a = acceleration
t = time
v = 0 + 1.5(5.25)
v = 0 + 7.875
v = 7.875m/s
v = 7.9m/s
