a) What is the value of the acceleration due to gravity on Unicorn in m/s2 ? b) How far from the base of the cliff does the rock land? A force of 40.0 N is required to pull the same rock at a constant velocity across a smooth glass surface on Earth. What force would be required to perform the same experiment on Planet Unicorn?

Physics You are on a mysterious planet with a gravitational acceleration of 2.0 m/s2. If you throw a ball straight upward with a speed of 10 m/s, how long will it take for the ball to return to where it was thrown?

A helicopter blade spins at exactly 110 revolutions per minute. Its tip is 9.5 m from the center of rotation. A. What is the average speed of the blade tip in the helicopter's frame of reference, in meters per second?  B. What is the average velocity over one revolution, in meters per second?

A golfer goes to chip the ball. The closest edge of the green is 60 m away and the furthest edge of the green is 80 m away. He hits the ball with an initial velocity of 30 m/s at a 40 degree angle. With this range, will the ball land on the green? O a. Yes O b. No

You live on a planet far from ours. Based on extensive communicationwith a physicist on earth, you have determined that all lawsof physics on your planet are the same as ours and you have adopted thesame units of seconds and meters as on earth. But you suspect that thevalue of g, the acceleration of an object in free fall near the surface ofyour planet, is different from what it is on earth. To test this, you take asolid uniform cylinder and let it roll down an incline. The vertical height hof the top of the incline above the lower end of the incline can bevaried. You measure the speed vcm of the center of mass of the cylinderwhen it reaches the bottom for various values of h. You plot v 2cm (inm2/s2) versus h (in m) and find that your data lie close to a straight linewith a slope of 6.42 m/s2. What is the value of g on your planet?

QUESTION 1 A skier leaves the 20 ski jump ramp at 10 m/s. Determine: a The distance d' where she lands on the 45° surface. b. The magnitude of her velocity just before she lands on the 45° surface. c. The time of flight. Take the gravitational acceleration to be 9.81 m/s² 20° 3m 45°

A car of mass 980 kg coasts at a constant speed of 18 m/s over a circular hill of radius 250 m. What is the magnitude of its acceleration, in m/s2?

To withstand “g-forces” of up to 10 g’s, caused by suddenly pulling out of a steep dive, fighter jet pilots train on a “human centrifuge.” 10 g’s is an acceleration of 98 m/s2. If the length of the centrifuge arm is 12 m, at what speed is the rider moving when she experiences 10 g’s?
