Question

1. The OntarioTech rowing team is moving along at a steady speed of 17.86 m/s. The cox issues an order to increase the rate of speed of the boat and the boat uniformly accelerates to reach a final speed of 41.1 m/s. If the boat traveled a distance of 53 m before reaching the final velocity, what was the boat’s acceleration over that distance?

An airplane accelerates down a runway at 13.7 m/s2 for 12.1 s until it finally lifts off the ground. What was the distance traveled before takeoff?

A coin is dropped from a height of 25.7 m. At what speed would the coin hit the ground? (answer can be positive since speed is directionless)

A running back carries the ball straight down the field at a velocity of 5.42 m/s. If the player is 12.2 m away from the goal line, how many seconds will it take the player to reach the goal line for the touchdown?

A soccer ball is kicked with an initial horizontal speed of 1.32 m/s and an initial vertical speed of 3.21 m/s. Assuming that the projection and the landing height are the same and neglecting air resistance, what would the ball`s horizontal speed be at the end of its flight?
