Assuming constant acceleration due to gravity, the skydiver's downward velocity after 2 seconds can be calculated using the equation v = u + at, where v is the final velocity, u is the initial velocity (usually 0 for objects in free fall), a is the acceleration due to gravity (9.8 m/s^2), and t is the time (2 seconds). Plug the values into the equation to find the downward velocity after 2 seconds.
The velocity after 2 seconds, 5 seconds, and 10 seconds can be calculated using the formula v = gt, where g is the acceleration due to gravity (approximately 9.81 m/s^2). After 2 seconds, the velocity is 19.62 m/s downward. After 5 seconds, the velocity is 49.05 m/s downward. After 10 seconds, the velocity is 98.1 m/s downward.
78.4 m/s
The velocity of a skydiver after two seconds would depend on factors such as air resistance, weight of the skydiver, and initial velocity. On average, a skydiver may reach a velocity of around 56 m/s (about 125 mph) after two seconds of freefall.
Assuming the object is in free fall, the change in velocity will be approximately 19.6 m/s downward. This is calculated using the formula v = at, where acceleration due to gravity is approximately 9.8 m/s^2 and time is 2 seconds.
The correct answer is B: 9.8 m/s downward. In free fall near the surface of the Earth, objects accelerate at a rate of 9.8 m/s^2 downwards due to gravity. After 0.10 seconds, the object's velocity would be 9.8 m/s downward.
The velocity after 2 seconds, 5 seconds, and 10 seconds can be calculated using the formula v = gt, where g is the acceleration due to gravity (approximately 9.81 m/s^2).

Acceleration of gravity near the surface of the earth is 9.8 meters (32.2 feet) per second2. Downward velocity after 2 seconds = 19.2 meters (64.4 feet) per second.
Assuming the object is in free fall, the change in velocity will be approximately 19.6 m/s downward. This is calculated using the formula v = at, where acceleration due to gravity is approximately 9.8 m/s^2 and time is 2 seconds.
The correct answer is B: 9.8 m/s downward. In free fall near the surface of the Earth, objects accelerate at a rate of 9.8 m/s^2 downwards due to gravity. After 0.10 seconds, the object's velocity would be 9.8 m/s downward.
A skydiver's velocity after 2 seconds will depend on factors such as their initial velocity, weight, air resistance, and gravitational force acting on them. On average, a skydiver will reach a terminal velocity of around 120 mph (193 km/h) after about 10 seconds of freefall.
The velocity of an object in free fall can be calculated using the equation v = gt, where g is the acceleration due to gravity (9.8 m/s^2). Plugging in the values, we get v = 9.8 m/s^2 * 9 s = 88.2 m/s. Therefore, the velocity of the 8 kg mass after 9 seconds is 88.2 m/s.
it would be 7
The change in velocity of the object would be 19.6 m/s downward. This is because the object accelerates at a rate of 9.8 m/s^2 due to gravity, and after 2 seconds, it has reached a velocity of (9.8 m/s^2) * (2 s) = 19.6 m/s.
The speed of an object in free fall after 2 seconds is approximately 19.6 m/s. This speed is the result of acceleration due to gravity, which is approximately 9.8 m/s^2 downward. After 2 seconds, the velocity of the object will be equal to this acceleration times the time, resulting in a speed of 19.6 m/s.
Assuming no air resistance, the velocity of the ball after 3 seconds can be calculated using the equation v = u + gt, where v is the final velocity, u is the initial velocity (0 m/s in this case), g is the acceleration due to gravity (approximately 9.8 m/s^2), and t is the time (3 seconds). Therefore, the velocity of the ball after 3 seconds would be 29.4 m/s downward.
