A marble rolls off a tabletop 1.0 m high and hits the floor at a point 3.0 m away from the table’s edge in the horizontal direction. (a) How long is the marble in the air? (b) That is the speed of the marble when it leaves the table’s edge? (c) What is its speed when it hits the floor?
A rescue helicopter is hovering over a person whose boat has sunk. One of the rescuers throws a life preserver straight down to the victim with an initial velocity of 1.40 m/s and observes that it takes 1.8 s to reach the water. (a) List the knowns in this problem. (b) How high above the water was the preserver released? Note that the downdraft of the helicopter reduces the effects of air resistance on the falling life preserver, so that an acceleration equal to that of gravity is reasonable.

ACTIVITY 3 PROBLEM SOLVING CIRCULAR MOTION Circular motion is another example of two-dimensional motion. When we analyze objects in circular motion, three quantities are used to portray it, hence speed, acceleration, and force. These factors are responsible in affecting the behavior of an object that is moving in circular path. Read, analyze, and solve the following problems using the GUFSA template. Show your complete solution. Round off your final answer to the nearest hundredths. 1. A 750-kg car moving at 8 m/s takes a turn around a circle with a radius of 20.0 m. Determine: a. the acceleration of the car b. the net force acting upon the car

What are the horizontal and vertical com- ponents of Harry's velocity just as he hits the water? b. Show that Harry hits the water at a speed of 25 m/s.
An airplane is delivering food to a small island. It flies 100 m above the ground at a speed of 160 m/s. a. Sketch the situation showing the flight and the parcel. Draw a motion diagram for the parcel during its flight showing both horizontal and vertical componenets of the velocity along the parcel's trajectory in one diagram. b.

A vertical upward kick is made with a ball. It goes via a speed gun set up 8 meters above the ground. As it rises, the speed gun registers 4.8 m/s. Don't worry about air resistance. Q1. What is the ball's takeoff speed? Q2. Assume the ball is kicked at an angle of 38 degrees above the horizontal with an initial velocity equal to its takeoff speed from the previous question. a.) How far can it reach?b.) How high can it get?c.) How long will it take to return to the ground?
