Problem 2 Civil Engineering students requires them to monitor the traffc safety at a busy intersection. They measwre (with a precision stopwatch) that exactly three seconds after car B passes through the intersection traveling south at ve = 55 mph, minivan A passes through at va = 70 mph on the road that runs at an angle 0 = 60° east of north. The speed of each automobile is constant. Determine (a) the relative velocity (in mph) of B with respect to 4, draw the vector triangles as part of vour answer (b) the change in position (in ft) of B with respect to A during a 10-s interval, (c) the distance (in ft) between the two automobiles 3 s after A has passed through the intersection.

Current Attempt in Progress In reaching her destination, a backpacker walks with an average velocity of 1.41 m/s, due west. This average velocity results, because she hikes for 6.94 km with an average velocity of 2.42 m/s due west, turns around, and hikes with an average velocity of 0.638 m/s due east. How far east did she walk (in kilometers)? VW 71 Number i West Units dw VE East dE

PROBLEM 2: If the coaster from a Zimmerman starts from rest at the peak and its speed increases at at = (6-0.06 S) m/s² going down to its trough, determine the magnitude of its acceleration when it reaches just before the trough where S = 40m and the radius of the curve is 79.30m. Ans. 6.03 m/s
A soccer ball is kicked from the ground with an initial speed of 20.2 m/s at an upward angle of 40.9*. A player 52.8 m away in the direction of the kick starts running to meet the ball at that instant. What must be his average speed if he is to meet the ball just before it hits the ground? Neglect air resistance.Use g=9.81 m/s?. Number i Unit

A cheetah is crouched 20 m to the east of a vehicle . Attime t = 0 the cheetah begins to run due east toward an antelope thatis 50 m to the east of the vehicle. During the first 2.0 s of the chase,the cheetah’s x-coordinate varies with time according to the equationx = 20 m + (5.0 m>s2)t2. Derive an expression for the cheetah’s instantaneous velocity as a function of time, and use it to find vx at t = 1.0 s and t = 2.0 s.

3) A particle is moving along the surface of a vertical cylinder. The motion is described by the relationships: r = A, 0 = 2nt and z = B sin(2nnt). In these equations A and B are constants and n is an integer. What is the magnitude of the velocity of the particle at an arbitrary time t? Take g = 9.81 m/s² when you need to use it.
