Answer: Your question does not make sense
Explanation:
You'd use the equation kinetic energy=mass*0.5*speed^2
So you'd rearrange this to get mass =kinetic energy /0.5 *speed^2
Which is mass= 1500J/0.5*35^2
=2.44897959183673469........kg

Answer:
I think it is C.
Explanation:
I took a 12 question quiz in USA TP and made a 92%. It won't let me see which one I missed though.
Look up habitat fragmentation and think about how well it answers the question given.
vf² = vi² + 2ad
vf = vi +at
vf = final velocity
vi = initial velocity
decelerated = a = - (negative)
a. stop ⇒ vf = 0
vf = vi+at
0 = 20 - 1.5t
1.5t=20
t = 13.3 s
b. vi = 20 m/s
0 = 20² - 1.5d
1.5d = 20²
1.5d = 400
d =266.67 m
c. d = vi.t -1/2at²
d = 20.3 - 1/2.1.5.3²
d = 53.25 m
