For a fixed initial speed, therange of a projectile isdetermined by the angle atwhich it is fired. For all but themaximum, there are twoangles that give the samerange. Considering factorsthat might affect the ability ofan archer to hit a target, suchas wind, explain why thesmaller angle (closer to thehorizontal) is preferable.When would it be necessaryfor the archer to use thelarger angle? Why does thestriker in a soccer game usethe higher trajectory?

The time of flight is directly proportional to the angle of projectile. The smaller angle is chosen…

Three blocks (1,2,3) of mass 3.00 kg, 2.00 kg, 1.00 kg sit block 1 block 2 block 3 linearly 10.0 cm apart from each other on a frictionless surface. •> 3kg A 25 g bullet is shot at the first block, it travels through the first block, and embeds itself into the second block (without falling over) which then collides into the third block. a. Assuming the final collision is elastic, and the third block has a final velocity of 5.00 m/s, what is the velocity of block 2 just before it collides into block 3? b. What is the velocity of the bullet before it embeds itself into block 2? c. Assuming the bullet slowed down by only 10% while it travelled through block 1, what was the speed of block 1 after the bullet traveled through it?

please answer in 20 minutes thank you! A 0.4 kg rubber ball has a horizontal velocity of 1.554 m/s at point A and goes through a projectile motion until it hits a smooth floor at point B. It then bounces off and reaches another peak in its trajectory at point C. The ball hits the smooth floor with an impact which has a coefficient of restitution of 0.8 in a very short span of time. Which of the following best approximates the speed of the ball just after it bounces off the floor for the first time? Which of the following best approximates the value of DISTANCE h?
