- A 160 g baseball is thrown with a speed of 20 m/s. It is hit straight back toward the pitcher at a speed of 40 m/s. The impulsive force of the ball registers at 0.60 milli seconds. What is the average force that the bat exerts on the ball?In a laboratory experiment, a 0.200 kg glider and a 0.400 kg glider are pushed towards eachother from opposite ends of an air track. The gliders have Velcro tabs on their bumpers. The 0.200 kgglider is pushed with an initial speed of 3.00 m⁄s, and the collision causes it to reverse direction at0.40 m⁄s. What was the initial speed of the 0.400 kg glider? Also can you draw a sketch alsoA sled filled with sand slides without friction down a 45 ∘ slope. Sand leaks out a hole in the sled at a rate of 3.2 kg/s. If the sled starts from rest with an initial total mass of 45.0 kg , how long does it take the sled to travel 100 m along the slope?
- Anthony is just relaxing since its summer vacation and actually put on some weight too and is now 90 kg. He decides to hit up Lake Thunderbird in his 40 kg boat and chill. Anthony reaches the center of the lake and stops moving and then decides to start fishing. He starts to fish but accidentally threw the 10kg pole at 5 m/s horizontally away from him. Suddenly, the boat starts moving. What is the velocity (magnitude and direction) of Anthony and the boat if the water really doesn’t have much friction with the boat?A 5.75 kg bowling ball moving at 9.20 m/s collides with a 0.860 kg bowling pin, which is scattered at an angle of 85.0° to the initial direction of the bowling ball and with a speed of 14.0 m/s. (Assume the bowling ball is initially moving in the +x-direction.) (a) Calculate the final velocity of the bowling ball. (Find the magnitude in units of m/s and direction in degrees counterclockwise from the +x-axis). magnitude m/s direction ° counterclockwise from the +x-axis (b) Is the collision elastic? O Yes O No (c) Linear kinetic energy is greater after the collision. Discuss how spin on the ball might be converted to linear kinetic energy in the collision.After skiding down a snow-covered hill on an inner tube, Ashley is coasting across a level snowfield at a constant velocity of +2.6 m/s.
