2.4 m/s". 1
Explanation:
A jet with mass m = 8 x 10* kg jet accelerates down the runway for takeoff at 2.4 m/s". 1
Answer:
i think it is To limit the rights of individual citizens
Explanation:
Answer:
The speed of the block when it is 5.00 m from the top of the incline is 3.04 m/s
Explanation:
given information:
s = 7.80 m
v = 3.8 m/s
if s = 5 m, v?
first we have to find the acceleration of the block using the following equation:
v² = v₀² + 2as, v₀² = 0 thus
3.8² = 2 a 7.8
a = 0.93
so, if s = 5m the final speed is
v² = 2 (0.93) (5)
= 9.26
v = √9.26
= 3.04 m/s
Answer:
Explanation:
Step one:
given data
initial velocity u= 40m/s
time taken t=3seconds
final velocity v=?
Step two:
applying the first equation of motion
v=u-gt--- (the -ve sign implies that the arrow is against gravity)
assume g=9.81m/s^2
v=40-9.81*3
v=40-29.43
v=10.57m/s
Step three:
how high the target is located
applying
s=ut-1/2gt^2
s=40*3-1/2(9.81)*3^2
s=120-88.29/2
s=120-44.145
s=75.86m
