Question

A motorboat starts from rest (initial velocity v(0) =v, = 0). Its motor provides a constant acceleration of 4 ft/s, but water resistance causes a deceleration of
400
ft/s. Find v when t= 5 s, and also find the limiting velocity as t+ o (that is, the maximum possible speed of the boat).
The velocity of the motor boat, v at t 5 s is ft/s.
(Round to two decimal places as needed.)

A chauffeur heads south with a steady speed of v, = 22.0 m/s for t, = 3.00 min, then makes a right turn and travels at v, = 25.0 m/s for t, = 2.40 min, and then drives northwest at v, = 30.0 m/s for t, = 1.00 min. For this 6.40-min trip, calculate the following. Assume +x is in the eastward direction. (a) total vector displacement (Enter the magnitude in m and the direction in degrees south of west.) magnitude direction ° south of west (b) average speed (in m/s) m/s (c) average velocity (Enter the magnitude in m/s and the direction in degrees south of west.) magnitude m/s direction o south of west

A ball is thrown off the top of a 30m cliff with horizontal velocity of 10 m/s. How far from the base of the cliff does the ball land? Express answer in meters.
The brakes on your car can slow you at a rate of 5.2 m/s2. (a) If you are going 137 km/h and suddenly see a state trooper, what is the minimum time in which you can get your car under the 90 km/h speed limit? (The answer reveals the futility of braking to keep your high speed from being detected with a radar or laser gun.) (b) Graph x versus t and v versus t for such a slowing.
Suppose that a motorboat is moving at 39 ft/s when its motor suddenly quits, and that 8 s later the boat has slowed to 19 ft/s. Assume that the resistance it encounters while coasting is proportional to its velocity, so that dv/dt = - kv. How far will the boat coast in all? The boat will coast feet. (Round to the nearest whole number as needed.)
A ball is shot from the ground straight up into the air with initial velocity of 45 ft/sec. Assuming that the air resistance can be ignored, how high does it go, to the nearest foot? The acceleration due to gravity is 32 ft per second squared.
