Answer:

38.64 feet

Explanation:

x=x0 + vx0t + 1/2axt2

x= 0 +  0  + 1/2 X 32.17 ft/sec2 X 1.55 sec2

x = 38.64 feet

You throw a 50.0g blob of clay directly at the wall with an initial velocity of -5.00 m/s i. The clay sticks to the wall, and th
Whitepunk [10]

Answer:0.25 kg-m/s

Explanation:

Given

mass of blob m=50 gm

initial velocity u=-5 m/s\ \hat{i}

time of collision t=20 ms

we know Impulse is equal to change in momentum

initial momentum P_i=mu

P_i=50\times 10^{-3}\times (-5)=-0.25 kg-m/s

Final momentum P_f=50\times 10^{-3}v

P_f=0 as final velocity is zero

Impulse J=P_f-P_i

J=0-(-0.25)

J=0.25 kg-m/s

A coin released at rest from the top of a tower hits the ground after falling 1.5 s. What is the speed of the coin as it hits th
Inessa05 [86]

initially coin is at rest and then it drop for total time t = 1.5 s

so here the speed of the coin at which it will hit the floor is to be find

v_f = v_i + at

here we know that

v_i = 0

a = 9.8 m/s^2

t = 1.5 s

now from above equation

v_f = 0 + 1.5 (9.8)

v_f = 14.7 m/s

so it will hit the floor with speed 14.7 m/s
