The velocity of a diver just before hitting the water is -10.9 m/s, where the minus sign indicates that her motion is directly d

Volgvan

velocity of the diver is vertically downwards

given that

$v = -10.9 m/s$

time of motion of the diver

$t = 1.17 s$

so the displacement is given by

$d = v*t$

$d = -10.9 * 1.17$

$d = -12.75 m$

so it will be displaced downwards by 12.75 m

When a quarterback throws a football, the throwing arm is slowed down to rest during the deceleration phase. Of the angular velo

asambeis [7]

Answer:

The deceleration is 4 times higher for 0.5sec than for 2 sec.

Explanation:

If the deceleration happens from 1800deg/sec to zero in 2 sec we have that the magnitude is:

$a_{1}=w/t_{1}=(1800deg/sec)/2sec=900 deg/sec^{2}$

if now the time to decelerate is 0.5sec:

$a_{2}=w/t_{2}=(1800deg/sec)/0.5sec=3600 deg/sec^{2}$

The deceleration is now 4 times higher than the previous situation.
