The process in which the nucleus of an atom splits into two lighter atoms, releasing a large amount of energy is nuclear

Initially, a particle is moving at 5.33 m/s at an angle of 37.9° above the horizontal. two seconds later, its velocity is 6.11 m/s at an angle of 54.2° below the horizontal. what was the particle's average acceleration during these 2.00 seconds in the x-direction (enter first) and the y-direction?

According to newton’s first law of motion, which force is expected to cause a body to accelerate?
