Answer:
a = 50 [m/s²]
Explanation:
This type of problem can be solved using Newton's second law, which tells us that the sum of forces on a body is equal to the product of mass by acceleration.
∑F = m*a
where:
F = force =25 [N] (units of Newtons)
m = mass = 0.5 [kg]
a = acceleration [m/s²]
Answer:
Kinetic energy
Explanation:
Kinetic energy is the energy of motion, and the arrow is in motion.
KE = 10 joules
ke = 1/2 x 0.8 x 5 x v2
