An antelope moving with constant acceleration covers the distance between two points 70.0 m apart in 7.00 s. Its speed as it passes the second point is 15.0 m/s. (a) What is its speed at the first point? (b) What is its acceleration? A car is stopped at a traffic light. It the...

in the first i chose last one but in second p mean density so the formula should be p=m/v m mass , v volume is not it ?

should we divied it , I mean solve it like x = 1/2at^2 ,x= bt^3 and take each part individual ! how can get red of (sin) from this formula , also here should i handle it individual !

if at^2 is distance, then a must be distance/time^2 okay but from where can i get distance ?! i mean as a number ! also here sin (C2 t) i think it is constant so we can't take dimension or i am wrong :( Again Thank u a lot :D

The equation for the change of position of a train starting at x = 0 is given by x=1/2at^2 + bt3 . Find the dimensions of a and b. If y = C1 sin (C2 t) where y is a distance and t is the time. What are the dimensions of C1 and C2 ?.

writeeacher i don't what u mean ! but i study this problems in physics any way i am sorry if i do any mistakes ! bobpursley thank u for help but should i convert it to k.g/m^3

The two masses in the Atwood's machine shown in the figure are initially at rest at the same height. After they are released, the large mass, , falls through a height and hits the floor, and the small mass, , rises through a height . Find the speed of the masses just befor...

A 1.9- block slides down a frictionless ramp, as shown in the figure. The top of the ramp is = 2.1 above the ground; the bottom of the ramp is = 0.40 above the ground. The block leaves the ramp moving horizontally, and lands a horizontal distance away. Find the distance .
