Answer:
B 23m/s
Explanation:
From the above information we get,
Initial velocity= 3m/s
Acceleration by gravity = 10 m/s2 (approx)
Time taken =2 seconds
v=u+at (First Equation Of Motion)
v= 3 + 10 × 2
v= 23 m/s
Answer:
Explanation:
As the final Kinetic energy is zero or less than initial kinetic energy, the collision must be inelastic.
In Inelastic collision both the bodies must stick together as final velocity is zero for both the bodies.
To conserve the momentum, momentum associated before the collision of first must be equal and opposite to the momentum associated with the second ball.
i.e.
Generally, the internal resistance of the new battery is small, about 0.2 euros, while the old battery is large, close to 1 euro ，
Answer:
Correct answer : v = 50 m/s
Explanation:
The movement described is a free fall with no initial velocity and we will use the following formula:
v = g · t we take that g = 10 m/s²
v = 10 m/s²· 5 s = 50 m/s
v = 50 m/s
