Frequency = 75 Hz. Speed = 45 m/s
= 100 cm ⇒ 45 m = 45 x 100 cm = 4500 cm
kinetic_energy = ½mv² = ½ × 45 kg × (10 m/s)² = 2250 Joules.
45 = 30 + m Subtract 30 from both sides: 15 = m
It is 45/100.
a 250 kg motorcycle moving at a speed of 45 m/s
1/45 m/s
speed = distance/time speed = 45/15 = 3 m/s
say shell velocity = 1000 m/s , launch angle = 45 deg from horizontal , then horizontal component = cos 45 * 1000 = 0.707 *1000 = 707 m/s
Ben's velocity can be calculated using the formula velocity = displacement / time. In this case, Ben's displacement is 45 m - 3 m = 42 m (since he ran from 3 m to 45 m west). Thus, his velocity is 42 m / 6 s = 7 m/s west.
8m/s west
The acceleration of the object can be calculated using the formula: acceleration = change in velocity / time taken. Given that the initial velocity is 25 m/s and the final velocity is 45 m/s, the change in velocity is 45 m/s - 25 m/s = 20 m/s. Without knowing the time taken, we cannot calculate the acceleration directly.
Frequency = 75 Hz. Speed = 45 m/s
The vertical component of the escalator's velocity at 45 degrees can be found by multiplying the given velocity (3 m/s) by the sine of the angle (sin 45° ≈ 0.7071). So the vertical component would be 3 m/s * 0.7071 ≈ 2.12 m/s.
45 meters is equal to 45,000 millimeters.
F = ma. F = 45 x 2 = 90 N.
= 100 cm ⇒ 45 m = 45 x 100 cm = 4500 cm
