What is the magnitude of the total force on a driver by the racing car he operates as it accelerates horizontally along a straight line from rest to `60m//s` in `8.0s` (mass of the driver`=80kg`)

What is the magnitude of the average acceleration of a skier who, starting from rest, reaches a speed of 8.0 m/s when going down a slope for 5.0 s ?

A 5kg mass is accelerated from rest to 60 m/s in 1 sec. what force acts on it:

A 5kg. mass is accelerated from rest to 60 m/s in 1 sec. what force acts on it:-

A 5kg. mass is accelerated from rest to 60 m/s in 1 sec. what force acts on it:-

A motorboat starting from rest on a lake accelerates in a straight line at a constant rate of 3.0 m//s^(2) for 8.0 s . How far does the boat travel during this time ?

A motorboat starting from rest on a lake accelerate in a straight line at a constant of 3.0 m s^-2 for 8.0 s. How far does the boat travel during this time?

In Fig a car is driven at constant speed over a circular hill and then into a circular valley with the same radius. At the top of the hill, the normal force on the driver from the car seat is 0. The driver's mass is 80.0 kg. what is the magnitude of the normal force on the driver from the seat when the car passes through the bottom of the valley?
