Rosa uses the formula (vi cos)t to do a calculation. which value is rosa most likely trying to find? the vertical acceleration of a projectile launched at an angle the vertical acceleration of a projectile launched horizontally the horizontal displacement of a projectile launched at an angle the horizontal displacement of a projectile launched horizontally

The motor m applies a time-varying force of f (200 t) n, where t is in seconds. box b with mass 200 kg starts from rest, and the coefficients of kinetic and static friction are 0.2 and us 0.3 the acceleration due to gravity is g 9.8 m/s2 b 300 a) find the time ' when the box starts to move. b) calculate the speed of the crate at 3 s c) calculate the power delivered by the motor at t 3 s

The voltage applied across a given parallel-plate capacitor is doubled. how is the energy stored in the capacitor affected?

The amount of work done is determined by 2 factors. describe an example of work (using the scientific definition) list the 2 factors that determine the amount of work done.
