A small toy gun fires light foam projectiles by compressing a spring. As the spring relaxes it pushes the projectile.
The toy gun has a spring with a spring constant of 484 N m−1, the spring is compressed by 5.00 cm, and it fires a 10.0 g projectile.
At what speed does the projectile leave the toy gun? (in m s−1 to 3 s.f)
1. Institutions refer to any structure or mechanism of social order and corporation governing the behaviour of set of individuals within a given human community. Within the context of institutions, discuss the following concepts in the African scenario
a) Decentralization and development
b) Privatization and development
A runaway 185 kg wheeled skip is rolling east along a road with a velocity of +2.2 m s−1. A 2560 kg car moving to the west with a velocity of −9.7 m s−1 hits the skip.
After the collision the skip is moving west with a velocity of −14.4 m s−1.
What is the velocity of the car after the collision? (in m s−1 to 2 s.f)
