50 pts a cyclist travels at distance of 400 meters in 120 seconds towards school, calculate his speed. (show your work) calculate his velocity if the direction is north east (ne) the cyclist in practice question 2, comes to a stop position within 15 seconds. calculate his acceleration. (show your work) is this an example of positive or negative acceleration?

1. Speed = 3.33333 Meters per second, 400/120=3.33333, average speed = total distance/elapsed time

2. Velocity = 3.33333 Meters, 400/120, V = distance / time

3. Acceleration = -0.222222, acceleration = (velocity2 - velocity1) / time

acceleration = net_force / mass

answer is : muchas/tipicas

have a nice day!
