A physics professor wants to build a spring-based nerf launcher. (a) Ignoring air resistance (which would be a bad idea in this case), if the launcher is to have a range of 100 m when fired at an angle of 45°, then what would the muzzle velocity of the launcher need to be? (b) Given that a nerf dart is about 1 gram, what would be the kinetic energy of the dart as it leaves the launcher? (c) If launcher's spring is compressed 20 cm prior to firing, then what would the spring constant of the spring used in the launcher need to be? Solve part (a) using kinematics since the time is your linchpin between the horizontal and vertical motion

It’s 5:00 PM and Kurdapya needs to finish her physics module, one of the problems states that a rocket and a spacecraft were attached and has a combined mass of 3.8×10^5 kg and is to reach a speed of 12.3 km/s, she needs to know how much kinetic energy will it have.
A block of mass m = 3 kg starts to slide from rest along a frictionless inclined surface thatmakes an angle of φφ = 300with respect to the horizontal surface.At the lowest points of the inclined surface, a projectile is fired at a speed of vv0 = 12 m/s thatmakes an angle θθ0 = 450 with respect to the horizontal. Our aim of this problem is to find thetime when the projectile will hit the block.
