Answer:
Step-by-step explanation:
Given that,
Height of the cylinder, h = 6 mm
Radius of the cylinder, r = 4 mm
We need to find the volume of the cylinder. The formula for the radius of the cylinder is given by :
Putting given values,
So, the volume of the cylinder is .
Given :
A particle moves in the xy plane starting from time = 0 second and position (1m, 2m) with a velocity of v=2i-4tj .
To Find :
A. The vector position of the particle at any time t .
B. The acceleration of the particle at any time t .
Solution :
A )
Position of vector v is given by :
B )
Acceleration a is given by :
Hence , this is the required solution .
