The blades in a blender rotate at a rate of 6200 rpm . when the motor is turned off during operation, the blades slow to rest in 4.3 s .
what is the angular acceleration as the blades slow down?

Aparticle initially moving east with a speed of 20.0 m/s, experiences an acceleration of 3.95 m/s, north for a time of 8.00 s. what was the speed of the particle after this acceleration, in units of m/s? give the answer as a positive number.

What does the law of conservation of mass state?

Both speed and velocity measure how fast something is moving. however, since speed is not a it does not require a(n question 6 options: a) quantity , unit b) magnitude, unit c) scalar, direction d) vector, direction
