Answer:
average force is 138900 N
Explanation:
given data
speed = 50 km/h = 13.89 m/s
mass = 1500 kg
time = 0.15 s
to find out
average force
solution
we know initial velocity of car is positive
we will apply here equation to find force that is
Force x change in time that is equal to mass x change in speed ................1
so put here all value of mass, time and velocity in equation 1
Force x 0.15 = 1500 x ( -13.89)
force = 138900 N
so average force is 138900 N
Answer:
14.2
Explanation:
find horizontal force of the weight = 2.5kg x 9.8 Sin30 = 12.3 N
to prevent the sliding she needs to pull horizontally
Fh = 12.3 /Cos 30 =14.2N
Answer:
Curl up test.
Explanation:
The curl up test is done to check the strength of the abdomen muscles and the stability of the core muscles. The strength of the core muscles determines the stability of the body.
The curl up test is done to test the abdomen strength and endurance and the strength of the back muscles.
The test requires the following materials: A flat cushioned surface(clean) and a measuring strip
- The measuring strip is placed on the mat under the students legs so that their fingertips are just resting on the nearest edge of the measuring strip. The feet cannot be held or rest against an object. Keeping heels in contact with the mat, the student curls up slowly, sliding their fingers across the measuring strip until the fingertips reach the other side, then curls back down until their head touches the mat. There should be 20 curl-ups per minute
If you provided the aforementioned line 19, that would kinda be great.
