Answer:
option B
−1.92 m/s2
Explanation:
Given in the question,
time took by truck to slow down = 3.56 sec
initial speed of truck = 112 km/h
final speed of truck = 87.4 km/h
1 km/h = 0.277778 m/s
112 = 31.1 m/s
87.4 = 24.28 m/s
Formula use to calculate the acceleration
v - u = at
where v is final speed
u is initial speed
a is acceleration
t is time
plug values in the equation
24.28 - 31.1 = a(3.56)
-6.8 = a(3.56)
a = -6.8 / 3.56
a = -1.9 m/s²
Answer:
10 your absolutely beautiful, don't let anyone else tell you otherwise.
Explanation:
Answer:
By applying a force of one Newton, one can hold a body of mass of 102 gram.
Explanation:
- Force is the pull or push of an object. It can be mathematically measured as, F= m* g.
where, F= force in newton
m= mass in kg
g= acceleration due to gravity (
)
F= m* 9.8
or, m= 
= 0.102 kg
or, m= 102 gram.
- Hence, 102 gram mass can be hold by one Newton force.
