A train slows down as it rounds a sharp horizontalcurve, slowing from 90.0 km/h to 50.0 km/h in the15.0 s that it takes to round the curve. The radius of thecurve is 150 m. Compute the acceleration at the mo-ment the train speed reaches 50.0 km/h. Assume thatthe train slows down at a uniform rate during the 15.0-sinterval.

Problem 2. The speed of a motorhoat in still waler is lour times the speed of a river. Normally, ihe motorboat takes one minute to cross the river to the port straight across on the other bank. One time, duc to a motor problem, it was not able to run at full power, and it took four minutes to cross the river along the same path. By what facior was the specd of the hoat in still water reduced? (Assume that the speed of the water is uniform throughout the whole width of the river.)
Starting from rest, the motorboat travels around the circular path, p = 50-m, at a speed v = 0.8t m/s, where 't' is in seconds. Determine the magnitudes of the boat's velocity and acceleration when it has p- S0 m traveled 20-m.
An object moving with constant acceleration along a horizontal path covers the distancebetween two points 60 m apart in 6.0 s. Its speed as it passes the second point is 15 m/s.Find a) the speed at the first point, b)its acceleration and c) the distance from the pointwhere the object was at rest to the first point.
Estimate by what factor a person can jump farther on the Moon as compared to the Earth if thetake off speed and angle are the same. The acceleration due to gravity on the Moon is one-sixthwhat it is on Earth.
Kilauea in Hawaii is the world’s most continuously active volcano. Very active volcanoes characteristically eject red-hot rocksand lava rather than smoke and ash. Suppose a large rock is ejected from the volcano with a speed of 25.0 m/s and at anangle 35.0º above the horizontal, . The rock strikes the side of the volcano at an altitude 20.0 mlower than its starting point. (a) Calculate the time it takes the rock to follow this path. (b) What are the magnitude anddirection of the rock’s velocity at impact?
At the 18th green of the U.S. Open you need to make a 23.5-ftputt to win the tournament. When you hit the ball, giving itan initial speed of 1.54 m>s, it stops 6.00 ft short of the hole.(a) Assuming the deceleration caused by the grass is constant,what should the initial speed have been to just make the putt?(b) What initial speed do you need to make the remaining 6.00-ft putt?
A particle moves in a straight line with the velocity shown in the figure. Knowing that s=-8m at t=0, plot the a-t and s-t curves for 0<t<20 secs. Determine the first value of "t" for which the particle passes throught the origin.
