Jason and Guy are throwing watermelons straight up from the ground. (They’re making fruit salad.) Jason throws his watermelon at
NISA [10]

Answer:2t

Explanation:

Given

Jason throwing watermelon at speed v and it spend t time in air

time to reach max height

v_f=u_i+at'

0=v-gt'

t'=\frac{v}{g}

and time to reach bottom is also t'

t=2t'

t=2\frac{v}{g}

For guy throws his watermelon at speed 2v

So total time in air will be

t''=2\frac{2v}{g}

t''=4\frac{v}{g}

t''=2t

An athlete performing a long jump leaves the ground at a 32.9 ∘ angle and lands 7.78 m away.part a )what was the takeoff speed ?
MatroZZZ [7]

Answer:

Explanation:

Given

Inclination \theta =32.9^{\circ}

Distance of landing point R=7.78\ m

Considering athlete to be an Projectile

range of projectile is given by

R=\frac{u^2\sin 2\theta }{g}

where u=launch velocity

7.78=\frac{u^2\sin (2\times 32.9)}{9.8}

u^2=83.58

u=\sqrt{83.58}

u=9.142\ m/s

(b)If u is increased by 8% then

new velocity is u'=9.87\ m/s

R'=\frac{u'^2\sin 2\theta }{g}

R'=9.07\ m
