You stand on the edge of a cliff and hold two metal balls, one in each hand. The mass and size of the metal
spheres are the same and we ignore the air resistance. One ball, ball 1, you drop outside the cliff. The other ball,
ball 2, you throw straight up. Which statement is correct for the acceleration of the metal balls after they have left
your hands:
A. a, = a2
B. a, > a,
C. a, < a,
D. a, = -a,

A sled starts from rest at the top of the frictionless, hemispherical, snow-covered hill shown in the figure. Find an expression for the sled's speed when it is at angle ø. Use Newton's laws to find the maximum speed the sled can have at angle ø without leaving the surface. At what angle ømax does the sled "fly off" the hill? R
a. How far does she travel in 8 s? 3.) The driver of mass 80 kg is strapped to the seat of his Ferrari. If she comes to a stop after traveling at 30 m/s in 2 s, determine the force on the driver from the seatbelt.
A pendulum is 0.850 m long, and the bob has a mass of 1.00 kg. At the bottom of its swing, the bob’s speed is 1.60 m/s. A) What is the tension in the string at the bottom of the swing? in N B)The tension is greater than the weight of the bob because a- its horizontal component is increasing from zero. b-the bob has a downward acceleration, so the net Fy must be downward. c- the bob has an upward acceleration, so the net Fy must be upward. d- the bob has zero acceleration.

An empty sled of mass 25 kg slides down a muiddy hill with a constant speed of 2.4 m/s The slope of the hill is inclined at an angle of 15 degrees with the horizontal. a. Calculate the frictional force on the sled as it slides down the slope b.Calculate the coefficient of friction between the sled and the muddy surface of the slope c. The sled reaches the bottom of the slope and continues of horizontal ground. Assume the same coefficient of friction. In terms of velocity and acceleration, describe the motion of the sled as it travels on horizontal ground.

A physics student, in a stationary elevator, places a 240.0 g mass on an electronic balance. The student hits the elevator button and it begins to move upwards. While the elevator is moving, the student records this information Time = 0 to 3.0 sec the balance reads 278 grams Time = 3.0 - 12 sec the balance reads 240. grams Time = 12.0 to 15.0 sec the balance reads 192 gram How far up (in meters) did the elevator travel? Consider: UP to be (+), DOWN to be (-) and g =9.8 m/s2 . ROUND YOUR ANSWER TO A WHOLE NUMBER of meters (no decimal places) HINT: This problem requires finding THREE different displacements and adding them up! 2nd HINT: You will need to (A) use your equations of motion or (B) make a v-t graph to find those displacements!
A water slide is connected so that a swimmer, starting from rest at the top of the slide, leaves the end of the slide travelling horizontally. one person hits the water 6m from the end of the slide in a time 0.4 seconds after leaving the slide. ignoring friction and air resistance, find the height H. b) how does the answer change if the swimmer leves the end at an angle of 10 degrees above the horizontal?
1. You are tasked with designing the runway on an aircraft carrier. The minimum speed for the F/A18 Hornet is 200 mph. The Hornet weighs 40,000 lbf and its twin engines provide a thrust of ~40,000 lbf combined, providing a max acceleration of 1g.a. How long must the deck be to takeoff unassisted? Give the answer in ft. b. This is most likely longer than your typical ~450 ft carrier. What acceleration must you achieve with both the engines and with a catapult system together to reach the required minimum speed by the end of the deck? c. What net force (combined engines and catapult) must be applied to the plane to get the acceleration in b? d. Do you think the plane will be able to use disk brakes on its tires to stop when landing?Use your knowledge of friction to make your argument. Also know that their coefficient of friction is ~1.
