As you push cereal box across a tabletop, the sliding friction acting on the cereal box

Aprojectile is launched horizontally 10m above the ground and with an initial velocity of 15 m/s. a) determine the magnitude and direction of projectile velocity at t= 1.3s b) determine the magnitude and direction of projectile acceleration at t=1.3s

The image shows a pendulum in simple harmonic motion the pendulum starts at a and swing to e

We put a force of 50n on an object and the acceleration is 100 m/s². what is the mass of the object?
