Answer:
a. Final velocity, V = 88 m/s
b. Distance, S = 960 meters
Explanation:
Given the following data;
Initial velocity = 8 m/s
Acceleration = 4 m/s²
Time = 20 seconds
a. To find the final velocity, we would use the first equation of motion;
V = u + at
V = 8 + 4*20
V = 8 + 80
Final velocity, V = 88 m/s
b. To find the distance covered, we would use the second equation of motion.
S = ut + ½at²
S = 8*20 + ½*4*20²
S = 160 + 2*400
S = 160 + 800
S = 960 meters
