Using the equation KE=1/2mv^2, plug in the numbers and solve for KE
Answer:
The answer depends on what object you are dropping. Are you dropping a balloon or a car? (I'm joking 'bout that one.) If the mass of the object is very little, then it might drop slower. If the mass is bigger, then it might drop faster.
Good luck!
Explanation:
Answer:
30 kgm/s
Explanation:
The momentum of a body is given by the product of mass and its velocity.
∴ momentum = mv
= 15 × 2
= 30 kgm/s
Answer:
C.Q/3
Explanation:
The total capacitances in series
1/C=1/C1+1/C2+1/C3
=1 /C+1/C+1/C
3/C
Ctotal=C/3
Charge in each capacitances
1/3*Q
