How much work is needed for a 73-kg runner to accelerate from rest to 7.7 m/s?
A projectile P of mass m is fired from a point 0 with initial speed v0 at launch angle φ0 above a horizontal firing range. In addition to gravity, P is subject to the aerodynamic drag force by the surrounding air modeled as a quadratic function of speed where v is the velocity of P and k is a positive pa- rameter. 0 0 We are interested in studying the effect of Faero on various aspects of projectile motion. Since...
EXPLORE A projectile is launched with a launch angle of 30° with respect to the horizontal direction and with an initial speed of 40 m/s. (A) How do the vertical and horizontal components of the projectile's velocity vary with time? (B) How long does it remain in flight? (C) For a given launch speed, what launch angle produces the longest time of flight? CONCEPTUALIZE Consider the projectile to be a point mass that starts with an initial velocity, upward and...
A 12-kW (16 hp) motorcycle can accelerate from rest to 20 m/s (45 mph) in 5.0 s. How much power does the motorcycle need to accelerate to the same speed in half the time?
An object is thrown vertically upward with a speed of 14.62mph. How much time from launch will it take to reach the bottom of a well 10.33 m deep?
An object with mAss Im is i along the +z direction. At time t = T it is at the pointz-2T and its speed is measured as v(T) nitially at rest at the origin -0.

a) In a television set the power needed to operate the picture tube comes from the secondary of a transformer. The primary of the transformer is connected to a 120-V receptacle on a wall. The picture tube of the television set uses 86 W, and there is 5.5 mA of current in the secondary coil of the transformer to which the tube is connected. Find the turns ratio Ns/Np of the transformer. b) A constant current of I = 15...
