Acceleration is the rate of change of the velocity of a moving object. To determine the speed the object has at a certain time, we need to determine the acceleration first by dividing the speed with the time given. We do as follows:
acceleration = 4.9 m/s / 5.1 s = 0.96 m/s^2
To determine the velocity after 7.1 s, we multiply 7.1 s to the acceleration.
speed or velocity = 0.96 x 7.1 = 6.52 m/s
Answer:
4 m/s
Explanation:
to find m/s, divide the meters term by the seconds term. 100m/25s = 4m/s
The formula for momentum is p=mv (mass multiplied by velocity), so in this problem, p=50(.5)=25=p or in other words, momentum.
