Ahorizontal force of 350n is exerted on a 2.5 kg ball as it rotates uniformly in a horizontal circle of radius of 0.90m. calculate the speed of the ball.

It is may 5 and you are somewhere in the northern hemisphere. if you determine that the noon sun is 51 degrees above your southern horizon, what is the latitude of your location

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

Akg a of 55 m at an of 11 ? . if is at 98 km/h,be ?
