Acar accelerates from rest to a velocity of 5 meters/second in 4 seconds. what is its average acceleration over this period of time? a: its acceleration is 1.25 meters/second. b: its acceleration is 5 meters/second. c: its acceleration is 0.8 meters/second. d: its acceleration is 1.25 meters/second^2. e: its acceleration is 20 meters.

While listening to operatic solos, musicians process the lyrics and the tunes in separate brain areas. this most clearly illustrates the functioning of different

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

Figure 9 on page 362 shows various motions of balls. the curved path followed by the yellow ball in b in picture b is result of a) inertia b) centripetal motion c) gravity and horizontal velocity d) linear motion
