KINEMATICS: The Speedboat Will Miss its Mark by What Distance?

A speedboat travels eastward at 80 knots (150 km/h) through a northward current of water moving 4.00m/s. Q1: What is the speedboat’s velocity vector relative to the starting port? What is the angle of travel?  Q2: If the boat’s captain wanted the boat to travel due east without getting off course, how far off courseContinue reading “KINEMATICS: The Speedboat Will Miss its Mark by What Distance?”

KINEMATICS: A Leap of Faith

A man leaps off of a 12m building into a large, 4 meter tall vat of quicksand. The man leaves the roof with a horizontal velocity of 18.0 miles per hour. ( 1.000 mi/hr = 0.4470 m/s ). Q1: A robot on the ground believes that the man is going to miss his mark, andContinue reading “KINEMATICS: A Leap of Faith”

KINEMATICS: The ” architecture of motion. “

Q: A mass m is moving horizontally across the surface of the earth with a velocity of ( v ) = 30 m/s . The mass approaches a ledge with an edge situated 100 m above the ocean. The mass eventually moves off the ledge and falls until it reaches the ocean’s surface. Calculate theContinue reading “KINEMATICS: The ” architecture of motion. “”

KINEMATIC EQUATIONS: What is the ball’s speed when it’s caught by the goalie?

Q: A soccer player kicks the ball toward a goalie that is 29.0 m in front of him. The ball leaves his foot at a speed of 19.5 m/s and at an angle of 33.4° relative to the ground. Find the speed of the ball when the goalie catches it in front of the net.Continue reading “KINEMATIC EQUATIONS: What is the ball’s speed when it’s caught by the goalie?”

KINEMATICS: What Initial Velocity is Needed to Propel a Projectile Over a Barrier?

Q: The highest barrier that a projectile can clear is 13.7 m, when the projectile is launched at an angle of 10.5° above the horizontal. What is the projectile’s launch speed? A: Recall that a projectile that travels in a curvilinear path has components of motion in the ( x ) and ( y )Continue reading “KINEMATICS: What Initial Velocity is Needed to Propel a Projectile Over a Barrier?”

KINEMATICS: How Far Will a Fired Projectile Travel?

Materials needed: ( 1 ) Spring-loaded cannon; ( 2 ) ruler; ( 3 ) timer The goal will be to determine how far a model cannon’s projectile will travel. First, we will theoretically determine the muzzle velocity ( vm ) of our model cannon. Position the cannon horizontally upon a table. Measure the vertical distanceContinue reading “KINEMATICS: How Far Will a Fired Projectile Travel?”
