Forward it is the same as the plane that he/she was jumping off.
Downward it is up to 300-350 kph.
The velocity of the person is the velocity of the speeding train plus the velocity of the jump out. this gives a resultant velocity with a forward component in the direction of the train's motion.
No. It depends on what other forces are acting on the object.
The skydiver's forward velocity after 1 second would depend on factors such as their body position, weight, and air resistance. On average, a skydiver in freefall might reach a forward velocity of around 120 mph (193 km/h) after 1 second.
When a skydiver jumps out of a hovering helicopter with forward velocity, the skydiver's initial velocity will be a combination of the helicopter's forward velocity and the vertical velocity due to gravity. As the skydiver falls, their acceleration is primarily due to gravity acting downward, with air resistance also playing a role. The acceleration experienced by the skydiver will be constant at approximately 9.8 m/s^2 downward, ignoring air resistance.
A projectile has an initial forward velocity.
A projectile has an initial forward velocity.
Of course. A car with brakes applied and slowing down has forward velocity and rearward acceleration.
Momentum = mass x velocity. You already stated the mass and velocity so you can figure out the momentum.
When velocity and acceleration are opposite in direction (velocity forward and acceleration backward, or vice versa), the object will slow down initially. This is because the acceleration is acting in the opposite direction of the velocity, causing the object to decelerate.
The skydiver's forward velocity can vary depending on factors such as body positioning, wind speed, and altitude. On average, a skydiver falling in a stable belly-to-earth position can reach speeds of around 120 mph (193 km/h).
Positive velocity refers to an object moving in the positive direction along its path. It indicates that the object is moving forward or in the direction of increasing position. Velocity is a vector quantity that includes both magnitude (speed) and direction.
1. force that moves a car forward is the friction force between the tires and the road (ignoring what is going on mechanically in the car) 2. if the car is travelling at constant velocity, net force is zero - forces pushing car forward are equal to forces pushing car back
