a boat moves through the water with 2 forces acting on it. one is a
2021N forward push by the motor on the propeller, and the other is an 1774N resistive force due to the water around the bow. What is the acceleration of the 1146kg boat? Answer in units of m/s^2.
would i use a=f/m for this...
A dragser and a driver together have a mass 905.5 the dragster, starting at rest, attains a speed of 25 m/s in .61s. find the average acceleration of the dragster during the time interval. answer in units of m/s.
ok I am assuming we have 3 variable for a kinematic equation t=.61s, v.=0, and...
A force is applied to a 1.7kg mass and produces 5.1m/s^2 acceleration.
what acceleration would be produced by the same force applied to a 8.5kg mass? answer in units of m/s^2
ok... would i just use a proportion to get the answer to the problem? 1.7/5.1 = 8.5/x? Or do i need to find the...
if i drop an apple while riding on a bus that is moving along a level road, and a pedestrian outside sees me do it... won't the pedestrian see motion at a curved motion downward with an initial vertical velosity?
A boat crosses a river of width 134m in which the current has a uniform speed of 1.24m/s. The pilot maintains a bearing (i.e. the direction in which the boat points) perpendicular to the river and a throttle setting to give a constant speed of 2.62m/s relative to the water.
What is the...
An object is released from rest on a planet that has no atmosphere. The object falls freely for 2.66m in the first second. What is the magnitude of the acceleration due to gravity on the planet? Answer in units of m/s^2
What kinematic equation would I use for this?
The initial speed of a body is 4.37 m/s. What is the speed after 2.06s if it accelerates uniformly at -3.93 m/s^2. Answer in units of m/s.
would I not use the kinamatic equ. v=v.+a(t) so v=4.37+-3.93(2.06)? cause when I do that I get the wrong solution?
