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 third one sliding friction
Explanation:
Answer:
734.215N
Explanation:
First we calculate the angle that corresponds to a 5% slope using the Tan-1 function
then we use the component that corresponds to the direction parallel to the road, additionally we must multiply by the gravity value to find the weight(g=9.81m/s^2)
Wx=M*g*sen(2.86)=1500kg*9.81*sen(2.86)=734.215N
Answer:
It is most likely option A B and C
