Answer: 5.79 s
Explanation:
Vs=0 m/s starting speed(from rest)
Vf=325 km/h= 325*1000/3600= 90.28 m/s
a=15.6m/s²
Using equation for acceleration we can find out time :
a=(Vf-Vs)/t
t=(Vf-Vs)/a
t=(90.28 m/s-0m/s)/15.6 m/s²
t=5.79 s
Answer: 
Explanation:
The acceleration of the motorcycle is given by Newton's second law:
where
F = 1295 N is the force applied to the motorcycle
m = 350 kg is the mass of the motorbike
a is the acceleration
By substituting the numbers into the formula, we find
Answer:
240 Joules
Explanation:
work = f x d
16 newtons is the force
15 meters is the distance
15*16= 240
Answer:
775 grams of ice
Explanation:
Heat loss by patient = heat gained by ice
Heat loss by patient = mass×specific heat capacity×(initial temperature - final temperature) = 62×4200×(40-39) = 260,400J
Heat gained by ice = mass × specific latent heat of fusion of ice = m×336000 = 336000m J
336000m = 260,400
m = 260400/336000 = 0.775kg = 0.775×1000 grams = 775 grams of ice
(150 km/hr) x (1000 m/km) x (hr/3600sec) = 41-2/3 m/sec
Acceleration = (change in speed) / (time for the change)
Change in speed = (41-2/3 minus 0) = 41-2/3 m/s
Time for the change = 0.5sec.
Acceleration = (41-2/3 m/s) / (0.5 sec) = 83-1/3 m/s² .
Acceleration of gravity = 9.8 m/s² .
Acceleration of sneezed air = (83-1/3) / (9.8) = <em>8.5 g </em>(rounded)
