Newton’s fifth law says so i’m sorry it’s just logic
Answer:
0.7m/s^2
Explanation:
acceleration=(final-initial velocity)/time
x=(14-0)/20
x=14/20
x=0.7
Answer:
gamma rays
Explanation:
because they have the highest in energy there fore it can cause some major damage
That latest value for the Angle is in Grads, not in Kilograms.
Apply law of conservation of momentum along vertical direction.


Apply law of conservation of momentum along the horizontal direction





The second ball velocity is 
The magnitud of final total momentum is

The magnitude of final energy is
