Chapter 5, Problem 95CP
On June 25, 1983, shot-putter Udo Beyer of East Germany threw the 7.26-kg shot 22.22 m, which at that time was a world record. (a) If the shot was released at a height of 2.20 m with a projection angle of 45.00, what was its initial velocity? (b) If while in Beyer’s hand the shot was accelerated uniformly over a distance of 1.20 m, what was the net force on it?

While you are on lookout duty at your fortress, you spot an enemy ship moving directly towards you with a constant speed of 15 m/s. At the moment when the ship is 1.5 km away, you fire a shell at an angle of 45 degrees above the horizontal, which hits the enemy ship. What was the initial speed of the shell to 2 sig figs?
The range of a projectile depends not only on v0 and but also on the value g of the free-fall acceleration, which varies from place to place. In 1936, Jesse Owens established a world’s running broad jump record of 8.09 m at the Olympic Games at Berlin (where g 9.8128 m/s2). Assuming the same values of v0 and , by how much would his record have differed if he had competed instead in 1956 at Melbourne (where g = 9.7999 m/s2)?
ANSWER QUICK!
An artillery crew demonstrates its skill by firing a shell at an angle of 88.0 degress and then lowering the gun barrel and firing a second shell at a smaller angle of 36.0 degress in such a way that the two shells collide in midair. The initial velocity of both shells is 930. m/s.
Find the time elapsed between the two firings, in seconds. Neglect air resistance.

- The citizens of Paris were terrified during World War I when they were suddenly bombarded with shells fired from a long-range gun known as Big Bertha. The barrel of the gun was 36.6 m long, and it had a muzzle speed of 2.20 km/s. When the gun’s angle of elevation was set to 55.0°, what would be the range? For the purposes of solving this problem, ignore air resistance. (The actual range at this elevation was 121 km; air resistance cannot be ignored for the high muzzle speed of the shells.) kmarrow_forwardA disucs thrower releases the discus with a horizontal velocity of 55 m/s and a vertical velocity of 35 m/s. what is the resultant velocity of the discus?arrow_forwardWhich equation is true when the height of a projectile is at its maximum?arrow_forward
