Answer: You throw an object upwards from the ground with a velocity of 20m/s and it is subject to a downward
acceleration of 9.8 m/s2. How high does it go?
Given Formula Set up Solution
vi=20 m/s
vf=0 m/s
a=-9.8 m/s2
x=?
vf
2 = vi
2 + 2a x (0 m/s)2= (20 m/s)2 + 2 (-
9.8 m/s2) x
x=20.4 meters
Explanation: i known/ i hoped that helped.
Answer:
The two different ways to measure gravitational potential energy is listed below:
Explanation:
- To measure the gravitational potential energy of the ball dropped from certain height we can use the formula as:
PE= mgΔh
where,
m= mass of the ball
g= gravity
Δh= change in height
- The second way is to follow the principal as:
Loss in PE = Gain in KE
∴ -ΔPE = ΔKE
- Height and mass is the major element that determines the gravitational potential energy of any object.
Answer:
8 meters/second
Explanation:
Rate x Time = Distance
R x T = D
R x 50sec = 400meters
R x 50sec/50sec = 400meters/50sec
R = 8meters/sec
Answer:
6500N
Explanation:
F = ma so therefore Were given mass (m) = 1500 kg, acceleration (a) = 5 m/s2, well have to calculate the force to be:
1500 x 5 = 6500 N
