The answers to the problem are as follows:
<span>a) use f=ma. Mass of student is 836/9.8=85.3kg, force is 935-836=99N. Put it into the formula you will get a=99/85.3
b)Use same formula. Force is 782-836=-54 so put it into formula a=-54/85.3
c)Stopping would take longer as the acceleration is smaller
I hope my answer has come to your help. God bless and have a nice day ahead!</span>
U = 0, initial vertical velocity
v = 60 mph = 88 ft/s
Ignore air resistance and take g = 32 ft/s².
It t = time to attain 60 mph, then
(88 ft/s) = (32 ft/s²)*(t s)
t = 88/32 = 2.75 s
Answer: 2.75 s
Answer:
Heat
Explanation:
This combo can cause weather such as tornados,hurricanes and storms.
Using p=v * i
p=250 * 0.8=200w = 0.2kw
power consumed in a day=0.2 *8=1.6 kwh
for one month=1.6 * 30 =48kwh
monthly bills= 48 *3 = Rs 144
Answer:
Kinetic Energy = 36 Joules
Explanation:
Given =
Mass = 2kg
Velocity = 6m/s
Solution =
Kinetic Energy = 1/2 × mv²
Kinetic Energy = 1/2 × 2 × 6 × 6
Kinetic Energy = 36 Joules
