If a ball is thrown vertically upward with a velocity of 160 ft/s, then its height after t seconds is s = 160t - 16t^2. If a ball is thrown vertically upward with a velocity of 160 ft/s, then its height after t seconds is s = 160t − 16t^2.
About 11 miles per hour.
16 ft./sec./sec.
An impulse is simply a change of momentum, and momentum is defined as mass x velocity; so you just divide the momentum by the mass to get the velocity. Note about the units: newton x second is the same as kilogram x meter/second2.
To ensure uniformly accelerated motion, the net force acting on the object must be constant. This means that there should be no change in the magnitude or direction of the net force throughout the motion. Other factors such as mass and friction should also be kept constant.

16 feet/second is the speed. To know the velocity, you would also need to specify the direction in which the object moves.
Substitute the 2 in for t.38(2)-16(2)^276-64=12

If it was thrown horizontally, it had an initial velocity of 10 meters/sec parallel to the ground. (It traveled 40 meters in 4 secs with no acceleration. x=vt) It also took 4 secs to travel vertically. It started with a vertical velocity of 0 m/s. Using x=v0 + (1/2) a t2 a = -g ( Acceleration due to gravity 9.8m/s2) x=0-(1/2)g*16 = -8 * 9.8 = -78.4 m It fell 78.4 meters before coming to a stop.

First Answer:Yes it does.Second Answer:Not so much. The most important thing is velocity, tracking, rotation, accuracy, and hitting the sweet spot or "pocket" of the pins. You will get more pin action from 16 pound ball than a 6 pound ball thrown with the same velocity though, so in broader general terms yes, but not from just a difference in a few pounds alone.

This question is all about kinetic energy. Kinetic Energy = 0.5 * mass * velocity^2 Firstly we must assume that no energy is lost to heat and sound, so that kinetic energy is constant throughout the contact. The initial kinetic energy is all in the 2kg metal ball. Using the above formula we find that the energy is 0.5 * 2 * 3^2 = 0.5 * 2 * 9 = 9 J The final kinetic energy must be the same (because of our assumption). The metal ball has a kinetic energy of 0.5 * 2 * 1^2 = 1 J, so the wooden ball must have the remainder, which is 8 J. 8 = 0.5 * 1 * velocity^2 velocity^2 = 16 velocity = square root of 16 velocity = 4 m/s
