An olympic shot putter is doing his thing; His shotput ball, with a mass of 6.00 kg,Iands 20.0 meters from where he launched it at a 45.0 degree angle.Assuming he accelerated the shot uniformly for 0.4000 seconds, and neglecting the acceleration distance and any height difference between launch and landing (both not quite truei)with how much force did he ,,put,,the shot?

In the metric drag races (a previously -unreported olympic event),the hottest cars cross the finish line at speeds of 100 m/s.Assuming these cars accelerate uniformly and continuously,what is the magnitude of their average acceleration if the drag track is 400 meters long?

In the Olympic trials,winner of the first heat takes 42 seconds to run the 400 meter sprint.This race completes one lap around the track (assumed to be exactly 400m in circumference), and the finish line is located at the same point on the track where the sprinters began their race.What was the average velocity of the race winner?

Some students have gone to visit Valley of Fire State park to study rock formations.They park their car and then begin walking to various interesting areas.First, they walk northeast (45%0 north of east) for 900.meters.Then,they walk 1.200 km in a direction 50.%0 north of west.Finally, they walk 0.700 km in a direction 30.0 south of west and then set up camp for the night.It took two hours for the students to walk from their car to their camp.

A How far is camp from the car (distance and direction (with respect to north)?

B What was the students, average speed between the car and camp?

C What was the students, average velocity between the car and camp?

Prior to the diving competition on Zarkon, one of the intragalactic divers kicks a stray meteor off the 10.0- meter diving platform.i.e.The top of the platform is 10.0 meters avove the water.) Assuming she kicks the rock horizontally off the board at a speed of 7.00 m/s;

(a) How long does it take for the rock to hit the water (or whatever you swim in on Zarkon)?

(b) How far from the base of the diving platform does the rock hit the water?(take the base of the platform to be directly below the edge facing the water)

(c) What is the speed of the rock when it hits the water?

Martha (a very fast cyclist )is riding her bike along a level, horizontal road when she unknowingly comes to a complete drop off (or cliff)at the end of the road. By remaining completely composed she lands perfectly on another level road exactly 121 m ahead and 18 m below and then continues on her way ( you may ignore air resistance).

a. Determine Martha ,s launce velocity along the original road (upon encountering the cliff).

b.Determine Martha,s total flight time.

c.Determine the velocity of Martha and her bike when she is exactly 12.5 m below the original road.
