A toy rocket operates by having a spring-loaded tube which ejects a small model rocket when released. The spring inside has a spring constant k = 625N/m, the rocket has a mass of 0.100 kg, and the maximum compression of the spring is 0.18 m.  At t2 when the rocket leaves the launcher, what is the speed of the rocket at this moment? show your work At t3 the rocket reaches the peak of its flight. What is the height at this point? Show your work

A bobsled zips down an ice track starting at 40 m vertical distance up the hill. Disregarding friction, what is the velocity of the bobsled at the bottom of the hill? (g = 9.81 m/s2) Show your work please.

A skateboarder, mass m is originally skating at a speed v when they encounter a halfpipe and end up at height h above the ground. A second skater, mass 2m starts with speed 3v. What is the maximum height the second skater will reach? Show your work.

A soccer player hits a 75g soccer ball that is traveling toward him at a velocity of 25 mph with a kicking velocity of 60 mph, at the point of impact. The time of impact is 0.025s. Assume the coefficient of restitution is 0.50. (Show all work) A.) How fast is the ball traveling after impact? B.) If the ball is hit at an angle of 30 degrees, how many seconds will it be in the air? C.) How many yards will the ball travel down the field? D.) What is the average impact force exerted on the leg during the kick?

A spring on Earth has a 0.500 kg mass suspended from one end and the mass is displaced by 0.3 m. What will the displacement of the same mass on the same spring be on the Moon, where the acceleration due to gravity is one sixth that of Earth? Show your work.

In the ballistic pendulum shown below, the block has a mass of 1.4 kg, the bullet has a mass of 0.0091 kg, and the string has a length of 2.62 m. A bullet is shot directly at the block, lodging into the block, and causing the pendulum to swing forward 20°. What was the initial speed of the bullet, in m/s? Be clear and show all your work.
