In a certain men's track and field event, the shotput has a mass of 7.25 kg and is released eastward with a speed of 17.2 m/s at 41.0
The initial horizontal components of the momentum of this shotput is,
Px = mvcos41o = 7.25*17.2*cos41o = 94.1 kg.m/s
The initial vertical components of the momentum of this shotput is,
Py = mvsin41o = 7.25*17.2*sin41o = 81.8 kg.m/s
The initial momentum is directed at 41o above the horizontal.

In a track and field event, a hammer thrower accelerates the hammer (mass = 7.30 kg) from rest within four full turns (revolutions) and releases it at a speed of 23.0 m/s. Assuming a uniform rate of increase in angular velocity and a radius of 1.60 m, calculate the angular acceleration.
The hammer throw is a track-and-field event in which a 7.2-kg ball (the ''hammer''), starting from rest, is whirled around in a circle several times and released. It then moves upward on the familiar curving path of projectile motion. In one throw, the hammer is given a speed of 23.0 m/s. For comparison, a .22 caliber bullet has a mass of 2.6 g and, starting from rest, exits the barrel of a gun with a speed of 400 m/s. Determine...
1. In a track and field event, a hammer thrower accelerates the hammer (mass = 7.30 kg) from rest within four full turns (revolutions) and releases it at a speed of 23.0 m/s. Assuming a uniform rate of increase in angular velocity and a radius of 1.40 m, calculate the angular acceleration. ___________ rad/s^2
1. In a track and field event, a hammer thrower accelerates the hammer (mass = 7.30 kg) from rest within four full turns (revolutions) and releases it at a speed of 22.0 m/s. Assuming a uniform rate of increase in angular velocity and a radius of 1.30 m, calculate the angular acceleration.
The hammer throw is a track-and-field event in which a 7.30-kg ball (the hammer) is whirled around in a circle several times and released. It then moves upward on the familiar curved path of projectile motion and eventually returns to the ground some distance away. The world record for the horizontal distance is 86.75 m, achieved in 1986 by Yuriy Sedykh. Ignore air resistance and the fact that the ball was released above the ground rather than at ground level....

In the javelin throw at a track-and-field event, the javelin is launched at a speed of 33.0 m/s at an angle of 36.5° above the horizontal. How much time is required for it to hit the target that is the same height across the field?
A m = 3.50-kg mass swings as a pendulum on a 37.0 m long string. (a) The mass is released from rest when the string is at an angle of 41.0° from the vertical. Find its speed at the bottom of the swing. m/s (b) What would be the speed the mass at the bottom of the swing if it had a speed of 4.60 m/s when the string is at an angle of 41.0° from the vertical. m/s
Two carts on an air track are moving toward each other. One has mass 2.0 kg and velocity -0.90 m/s, and the other has mass 3.0 kg but unknown speed. They collide in a totally inelastic collision, and move with velocity +1.2 m/s after the collision. What was the initial speed of the second cart (in m/s)?
