Answer:
C
Explanation:
horizintal speed stays same
only vertical speed changes
so H speed will stay 30 m/s
Answer:
= 15.57 N
= 2.60 N
= 16.98 N
The mass of the bag is the same on the three planets. m=1.59 kg
Explanation:
The weight of the sugar bag on Earth is:
g=9.81 m/s²
m=3.50 lb=1.59 kg
=m·g=1.59 kg×9.81 m/s²= 15.57 N
The weight of the sugar bag on the Moon is:
g=9.81 m/s²÷6= 1.635 m/s²
=m·g=1.59 kg× 1.635 m/s²= 2.60 N
The weight of the sugar bag on the Uranus is:
g=9.81 m/s²×1.09=10.69 m/s²
=m·g=1.59 kg×10.69 m/s²= 16.98 N
The mass of the bag is the same on the three planets. m=1.59 kg
Im saying a or b but i pick B
Answer:
v=14.14 m/s
t=1.141 s
Explanation:
Given that
h = 10 m
Initial velocity ,u = 0 m/s
We know that acceleration due to gravity g= 10 m/s²
Lets take final velocity = v
Final velocity v is given as
v² = u²+ 2 g h
v²= 0² + 2 x 10 x 10
v²= 200
v=14.14 m/s
Time taken t is given as
v= u + a t
a=acceleration
t=time
Now by putting the values in the above equation we get
14.14= 0 + 10 x t
14.14 = 10 t
t=1.141 s
