a dog is running at 9.5ms and is 40m behind a rabbit moving at 5.5ms. how long will it take the dog to catch the rabbit and how far did they travel?

Below is the description of the position in meters of the puck as it moves in the x plane where t is in seconds x= 4t^3 + 2t^2 + t. A. How long did the puck move after 2 seconds B. What is the velocity of the puck at 2 seconds? C. What is the acceleration of the puck at 2 second?

A race car is moving at a constant speed of 5.9m/s in a clockwise direction on a circular track of radius 128m. What is in m/s^2 it's tangential velocity at that time?

a particle is rotating about an axis in x-y plane then find out the turning moment of the particle about the axis of rotation

MOTION IS ALWAYS ALONG STRAIGHT LINE... IF SO THEN WHY EARTH MOVES ALONG AN ELLIPTICAL ORBIT..?

A
ball P of mass 0.25kg loses one-third of its velocity when it make a
head on a collision with an identical ball Q at rest .After collision,Q
moves off with a speed of 2m/s in the original direction of p.Calculate
the initial velocity of P?

when two balls are projected horizontally from the same point and velocity, but the time difference for the second ball to projected is just one second after the first one, at what point in the motion will the balls be closest to each other?

A hiker sets out on a trek heading [N35degreesE] at a pace of 5.0km/h for 48.0 min. He then heads west at 4.5km/h for 40.0 min. Finally, he heads [N30degreesW] for 6.0km/h, until he reaches the camground 1.5 hours later. What is his total displacement?

1 newton is represented as

why is the curve radius minimum when a projected ballistic ball reaches the maximum height?
