Answer:
Part a)

Part b)

Part c)

Explanation:
As we know that acceleration is rate of change in velocity of the object
So here we know that


Part a)
differentiate x and y two times with respect to time to find the acceleration






Now the acceleration of the object is given as

at t= 1.1 s we have

now the net force of the object is given as



now magnitude of the force will be

Part b)
Direction of the force is given as



Part c)
For velocity of the particle we have




now at t = 1.1 s

now the direction of the velocity is given as



 
        
             
        
        
        
The magnitude of the net displacement is 95.3 m
Explanation:
To find the magnitude of the net displacement, we have to resolve each of the two displacements into the horizontal and vertical direction first.
1st displacement is:
 at
 at 
So its components are

2nd displacement is:
 at
 at 
So its components are

Therefore, the x- and y-components of the net displacement are:

Therefore, the magnitude of the final displacement is:

Answer:

Explanation:
First of all let's define the specific molar heat capacity.
 (1)
 (1)
Where:
Q is the released heat by the system
n is the number of moles
ΔT is the difference of temperature of the system  
Now, we can find n with the molar mass (M) the mass of the compound (m).
 
       
Using (1) we have:
