They're the largest bears in the world and they've been clocked at 41 [mph] and they've run a hundred meter dash in 5.85 seconds which human on stimulants doesn't even approach. a. Compute the speed of a grizzly bear using Mr. Treadwell's hundred-meter statement. b. Compute the momentum of a grizzly bear using the speed you calculated in part a. and the average mass stated by Mr. Treadwell. c. How fast would a 250 lb man have to run to have the same momentum you calculated in part b? d. How fast would a 4000 lb car have to drive to have the same momentum you calculated in part b?It changed but I tried putting the right input but it didn’t work so now I have to find what equals to 374J

- 1. A student runs to school, covering a distance of 0.50 km in a direction of [N20^0 E] as measured from the starting point. She then trudges over to a friend's house 0.30 km away [W] from the school. The two friends then go off to the mall that is 0.8 km [W50^0S] from the friend's house. *You will need to draw the x and y components of the vectors a. What is the total displacement of the student? b. If the total time taken by the student to run to school then trudge over to the friend's house was 25 minutes, what was her average velocity? *There are many steps to this answer, ensure that you have included ALL steps.Bob has just finished climbing a sheer cliff above a beach and wants to figure out how high he climbed. All he has to use, however, is a baseball, a stopwatch, and a friend on the ground with a long measuring tape. Bob is a pitcher, and knows that the fastest he can throw the ball is ?0=86.0 mph.v0=86.0 mph. Bob starts the stopwatch as he throws the ball (with no way to measure the ball's initial trajectory) and watches carefully. The ball rises and then falls, and after ?1=0.710 s,t1=0.710 s, the ball is once again level with Bob. Bob cannot see well enough to time when the ball hits the ground. Bob's friend then measures that the ball landed a distance of ?=354 ftx=354 ft from the base of the cliff. How high up is Bob if the ball started from exactly 5 ft above the edge of the cliff?Hi, please use the numbers that are provided in the problem to solve this for me please.
