Spaceship 1 and Spaceship 2 have equal masses of 200 kg Spaceship 1 has a speed of 0 m s and Spaceship 2 has a speed of 6 m s They collide and stick together What is their speed?
3 m/s
If a fighter is landing on an aircraft carrier's flight deck that has a length of 300 m must reduce its speed from 153 km to exactly 0 km in 2 s what is the jet's acceleration?
To find the acceleration of the jet, we first need to convert the speed from km/h to m/s. 153 km/h is equal to 42.5 m/s. The final velocity is 0 m/s, so the change in velocity is 42.5 m/s. The acceleration can be calculated using the formula acceleration = change in velocity / time. Therefore, the acceleration of the jet is 42.5 m/s divided by 2 s, which equals 21.25 m/s².
What is the velocity after 8 seconds as it falls freely from rest?
Ignoring air resistance:acceleration due to gravity is approx 9.81 m/s²Using Newton's equation of motion:v = u + atwhere:v = final velocity (to find)u = initial velocity = 0 m/s as it was at resta = g - acceleration due to gravity (in a downward direction)t = 8 sv = 0 + g × 8 = 8g (downwards) Taking g as 9.81 m/s² this makes the final velocity v ≈ 8 s × 9.81 m/s² = 78.48 m/s ≈ 78.5 m/s
What does one third times s plus 6 equals 3n equal?
s = 9n - 18.
What is five twelfths plus one third equal?
9/12's
