A golf ball with a mass of 43.00 g can be blasted from rest to a speed of 71.10 m/s through impact with a club head. Suppose that the impact lasts only about 1.100 ms.
1. Compute the change in momentum of the ball.
2. Compute the average force applied.
A moderate wind accelerates a pebble over a horizontal xy plane with a constant acceleration. At time t = 0, the velocity is. What are the (a) magnitude and (b) angle of its velocity when it has been displaced by 13.0 m parallel to the x axis?
Consider a rocket launched from Vandenberg AFB, CA (longitude=34.6 degrees) having an initial velocity of 3 km/s in the northerly direction relative to the launch site.
How many radians does the turntable rotate from the time it is turned off until it stops? (Assume constant angular acceleration.)
The simple harmonic oscillator can be used as a model for the vibration of a diatomic molecule. Mass and Force Constant are on the order of 10^?26 kg and 10^3 N/m. This model will work if the temperature is sufficiently low (we assume it is in the gr..
calculate the emission temperature of the earth, if the planetary albedo is changed to that of ocean areas without clouds, about 10%
A constant force is applied to an object, causing the object to accelerate at 10 m/s2. What will the acceleration be if the force and the object's mass are both halved? What will the acceleration be if the force is halved and the object's mass is dou..
A constant friction force of 25 Nacts on a 65 kg skier for 20 s. What is the skier's change in velocity
