a star that suddenly increases greatly in brightness because of a catastrophic explosion that ejects most of its mass.
Formula:
F = ma
F: force (N) m: mass (kg) a: acceleration (m/s^2)
Solution:
F = ma
F = 20 × 10
= 200N
So you would divide 1530 by 8 and that’s how you’d get your answer, so it should be (blank)m
Explanation:
the object has constant velocity for 2 seconds and it get a constant accelration (2ms-2)
Answer:
Vy = 26 m/s sin 30 = 13 m/s vertical speed
t = Vy / a = 13 m/s / 9.80 m/s^2 = 1.33 sec time to reach Vy = 0
H = Vy t + 1/2 g t^2
H = 13 m/s * 1.33 sec - 1.33^2 * 9.8 / 2 m = 8.62 m
