The driver of a car sets the cruise control and ties the steering wheel so that the car travels at a uniform speed of 14m/s in a circle with a diameter of 100m . Part A Through what angular distance does the car move in 4.00min ?
A baseball player pops a pitch straight up. The ball (mass 230g ) was traveling horizontally at 36.0m/s just before contact with the bat, and 21.0m/s just after contact. Part A Determine the magnitude of the impulse delivered to the ball by the bat. Part B Determine the direct...
How much power must you exert to horizontally drag a 21.0kg table 15.0m across a brick floor in 20.0s at constant velocity, assuming the coefficient of kinetic friction between the table and floor is 0.500?
The acceleration due to the moon's gravity at its surface is less than what it is here on the surface of the earth. The computed value of 1.6 m/s2 is consistent with what the Apollo Program astronauts observed during their explorations there. Imagine an astronaut holding a...
For X ∼ Poi(λ), show that E(X) = λ and V ar(X) = λ. (Hint: Find E[X(X − 1)] = E(X2 ) − E(X).)
The Geometric distribution is used when we want to ﬁnd the probability of performing a sequence of trials with X failures before the ﬁrst success, where a success occurs with some probability p. We can denote such a random vari...
