Answer:
-150 N
Explanation:
(Newton's second law) F=ma
Sum of forces in Y direction= (+200 N)+(-200 N)= 0...
forces cancel, object does not accelerate up/down
Sum of forces in X direction= (+65 N)+(-65 N)+(-150 N)
= -150 N
notice that the +/- 65 components cancel, leaving a net force of 150 N in the LEFTwards direction (which is typically defined as negative)
Overall, the net force is -150 N
Answer:
50 x 3000 = 150000/4000 = 37.5
37.5 I think.

Hope this helps!
Answer:
Must be put in to break the bonds in the reactants and the energy that is released upon making the bonds in the products.
Explanation:
The heat energy is absorbed to break the chemical bonds, which are responsible for the attractive interactions between atoms and molecules, and which gives stability to chemical compounds. While the heat energy is released upon making the bonds in the chemical compounds.
Answer:
9m/s²
Explanation:
Given parameters:
Initial velocity = 30m/s
Final velocity = 0m/s
Distance traveled = 50m
Unknown:
Deceleration = ?
Solution:
To solve this problem, we apply the proper motion equation;
V² = U² + 2aS
V is the final velocity
U is the initial velocity
a is the acceleration
S is the distance
Insert the parameters and solve;
0² = 30² + 2(a)50
-900 = 100a
a = -9m/s²
The negative value indicates deceleration.
The motorcycle decelerates at a rate of 9m/s²
Answer:
Acceleration, a = 750m/s²
Explanation:
Given the following data;
Radius, r = 0.31m
Velocity, v = 15m/s
To find the centripetal acceleration;
Substituting into the equation, we have;
Acceleration, a = 750m/s²
Therefore, the centripetal acceleration of the bike wheel is 750m/s².
